About this game

Fifty nine percent love


"Summer Event Book" is a visual novel game, and the complete game process is about 12 hours.

A well-known writer wrote such a description on the girdle of one of his best-selling books, "100% love novel", because of this book, and because of this girdle, I sprouted the idea of making "Summer Event Book" Original intention "100% love game". But unfortunately, despite all efforts, the goal of "100% love game" is still out of reach.

Fifty-nine, up to fifty-nine, failed!

So, please allow me to call "Summer Event Book" a "fifty-nine percent love game" with the cheek.


Only you can heal my heart

There is nothing more comforting than a beautiful girl's smile.

So, I put all my love and fantasies into a beautiful girl who laughs, even if the girl is not human. For this reason, "Summer Event Book" may be regarded as an "electronic love letter", a confession letter to the "perfect girl in my heart". It would be great if you could have a little bit of empathy when reading this "electronic love letter", if you could be warmed and comforted by such a "perfect girl who loves to laugh".

I wish you in front of the screen to find your "perfect girl" even if it's only in your "heart" or "dream".


About the Game

"The big boy wearing a fox mask is not a human being. Once he is touched by a human being, he will disappear." From the first time I saw it back then, to now and then revisiting it from time to time, this story makes me cry every time.
Even such a perfect big boy cannot have perfect love, even if it is exchanged with his life.
Love is like this, life is like this, life is like this,
The story of "Summer Event Book" also begins from this, rewriting this extremely gentle but also extremely regrettable ending.
"A monster girl who falls in love with humans will turn into thousands of fireflies and disappear in an instant" is an irresistible "rule" of nature.
But love is irresistible, love is "out of control" in all circumstances. The two who can't really get close, but the bond is getting deeper and deeper, and it even becomes the only reason for each other to live in this world.
So, what choice should you make?
perhaps,
This seems to be a dilemma for which there is no cure.
You have been given a mission to start a new adventure in your life, and it's up to you to make a difference.
perhaps,
This is fate,
But at the same time, it is for "you" who is living alone and living well,
Offer a bouquet of love.

    A Comic Love Story: LKY, Summer Case Files, and a Little Girl

    LKY loved comics. Back in the 90s, in his hometown, there were roadside book stalls—simple setups tucked into alleyways: two or three shelves, five or six tiny stools. Novels cost 3.5 cents per volume, while comics were just 1.5 cents. You couldn’t borrow them; you could only read on-site. With limited stools but plenty of readers, LKY often squatted against a wall, absorbed in reading for entire afternoons.Back then, LKY’s favorite manga artists were Akira Toriyama, Masami Kurumada, Rumiko Takahashi, and Tsukasa Hojo. If he had to pick just one, it would be Rumiko Takahashi. Not because of Ranma ½ or Urusei Yatsura, but because of Koisuru Kisetsu—also known as Maison Ikkoku. At the time, Inuyasha hadn’t even been released yet. Even after Inuyasha became a phenomenon later on, Koisuru Kisetsu remained LKY’s all-time favorite manga.He remembered he’d been chasing after Peacock King by Shungicu Uejima, but it was so popular that every time he went to the stall, someone else had already grabbed it. Since Ranma ½ was great, LKY picked up Koisuru Kisetsu from a pile of shoujo manga—and fell head over heels.Well, there was a little side story to that “falling head over heels,” but rest assured, it was absolutely because Koisuru Kisetsu was so good, not because she was so pretty.It was a summer evening. LKY, back then just a third- or fourth-grader, was reading Koisuru Kisetsu. He couldn’t remember which volume anymore—only that the story was getting really good. His backpack was cushioning his bottom as he leaned against the wall, completely absorbed. After a while, he caught a whiff of peaches. A little girl with a ponytail had squatted down beside him, intently reading the same manga in his hands—Koisuru Kisetsu. LKY froze. The page he’d been about to turn stopped mid-flip. When the next page didn’t come, the girl looked up. Their eyes met. Boom. Something exploded in LKY’s mind. He quickly lowered his head, pretending nothing had happened, and resumed reading Koisuru K...

    "Gratitude in Heart, Yet Ashamed to Accept It" - Delay Announcement

    Opening Ramble: For LKY, anxiety has become the norm. Every time LKY needs to announce a delay, sleepless nights follow. Even if LKY manages to fall asleep at two or three in the morning, waking up at 5:30 AM is inevitable. Feeling extremely tired but unable to get back to sleep. Each delay announcement requires LKY to build up psychological strength for a long time, from initially one day to now three or four days. The "Summer Case Files" being delayed by almost a year has been torturous for those who care about it and equally so for LKY. It torments LKY's spirit and body, as well as LKY's wallet. An extra year has added a significant burden, nearly becoming the last straw that breaks the camel's back. But having come this far, ending up in such a situation, just like LKY described "Summer Case Files" during crowdfunding, it's something LKY caused and must bear alone. LKY has some minor strengths but also significant flaws. This flaw led LKY from favorable circumstances into adversity, even dire straits. Overestimating one's capabilities while underestimating the complexity of each work process. Constantly making plans that are unachievable, feeling anxious and distressed as deadlines loom, paying the price over and over again, turning a good hand into a mess. From owning a car, a house, savings, a wife, and children, LKY has become someone who only orders cheap takeout meals, not even planning to return home for the New Year. "Summer Case Files" represents a new beginning for LKY, a form of atonement. LKY has poured years of debt and guilt into this game. But in truth, it's also extremely selfish, because LKY believes that "the purpose of an apology is to make oneself feel better. It does nothing to mend the harm caused." Yet there's no other way but to apologize first and then find a way to make amends. To express the desire to apologize through the game and then compensate with future efforts. Regarding this delay: This delay has little to do with the progress o...

    Summer Fantasy officially launches on January 15, 2025.

    Dear Supporters, I am reaching out to you with a heavy heart and a sincere plea for understanding. We had initially planned to launch "Summer Incident Records" on January 3, 2025. However, due to unforeseen circumstances, we must now postpone the release until January 15th of this month. I sincerely apologize for any inconvenience this may cause. As the primary person responsible for all aspects of "Summer Incident Records" apart from programming, I have been unable to focus on promotional activities until now because of the ongoing development work. Seeing the low number of wish list entries on our Steam page has been disheartening. The original plan was to provide an early release as a token of appreciation to those who have supported me throughout the development process. Yet, after many sleepless nights considering the upcoming release, I have decided to make another announcement in hopes of gaining your understanding and support once more. Over the past ten days, we've initiated some promotional efforts which have shown promising results. This success has reignited my hope that there is still much more we can achieve through further marketing. Due to personal limitations in time and resources, these efforts have been limited. However, even small steps have proven effective, and I would like to ask for your permission to dedicate the next two weeks to intensifying our promotional campaign. A sufficient number of wish list entries on Steam are crucial for the successful launch of our game. Although two weeks is a short period, it represents one last effort to ensure we do not leave any stone unturned. If you are passing by and reading this, I kindly ask for your support by adding "Summer Incident Records" to your Steam wish list. Your gesture would be greatly appreciated. Thank you for your continued support and understanding. Warmest regards, LKY and the "Summer Incident Records" Team
