One Slip-Up!! A
Game synopsis
The protagonist, Shuichi Sugiyama, belongs to the tennis club—a weak little club with only five members.
Though the club is practically ignored by everyone at school, for Shuichi it's a comfortable, reassuring place to be.
At its head is the troublemaking club president, Senpai Date, along with his willful and competitive little sister, Mio Sugiyama;
the sports-challenged advisor, Rika Hayama, and his childhood friend and best buddy, Hotaru Matsuoka.
There's also his innocent, honest, and slightly airheaded classmate, Ai Saeki.
Surrounded by these colorful companions, club activities are always full of fun and laughter.
However, with the incident of Shuichi getting injured as a turning point, the world around him begins to gradually change.
Seeing Ai care for Shuichi so attentively, his sister Mio somehow starts feeling out of sorts.
Amid this uneasy atmosphere, a major event finally occurs that completely upends the situation...
Senpai Reiko, whose intentions are anyone's guess—Shuichi actually gets kissed by her.
And to make matters worse, that moment is witnessed on the spot by two people, causing a huge uproar.
Ai is slowly starting to fall for Shuichi.
Mio is full of hostility toward this interloper who's come between her and her brother.
Caught between the two of them, Shuichi's days grow more and more headache-inducing.
Yet after the tennis club's summer training camp, a certain feeling gradually takes shape in his heart.
Is it a feeling for the classmate he admires? Or a feeling for his beloved little sister?
Or perhaps, a feeling for another important person besides the two of them...?
虽然这个社团在学校里几乎无人问津,但对修一来说,这里却是一个轻松自在、令人心安的地方。
以爱惹事生非的部长伊达学长为首,还有任性又好胜的妹妹杉山澪;
运动白痴的顾问羽山璃花,以及他既是青梅竹马又是挚友的松冈萤。
还有纯真坦率但有点天然呆的同班同学佐伯蓝。
被这群个性鲜明的伙伴们包围着,社团活动总是充满欢乐的气氛。
然而,以修一受伤这一事件为转折点,他周围的环境开始逐渐发生变化。
面对悉心照顾修一的蓝,妹妹澪不知为何心情变得不太好。
在这种不安的气氛中,终于发生了一起彻底改变局势的大事件……
不知究竟有多认真的黎子学姐。修一竟然被她亲了。
而且更不巧的是,这一幕被两人当场目击,引发了轩然大波。
渐渐开始对修一动心的蓝。
对这个插足自己与哥哥关系的存在充满敌意的澪。
被这两个人夹在中间,修一的日子变得越来越头疼。
然而,经过网球部夏季集训后,他心中也逐渐成形了一种情感。
那是对心仪的同班同学的情感吗?还是对珍爱的妹妹的情感?
又或者,是针对她们两人之外,另一个重要的人的情感呢……?
