Osananajimi no Onnanoko ga Zubunure de Ie ni Oshikakete Kita!!

A familiar face from the past makes an unexpected and dramatic return in this one-shot story. The protagonist's childhood friend—a girl he spent countless hours playing with during their younger years—suddenly arrives at his home completely drenched from head to toe. Her unannounced, soaked appearance immediately disrupts his ordinary day, leaving him bewildered as to why she would show up at his doorstep in such a state without any prior warning or explanation. However, her sudden arrival brings about more than just surprise over the rain-soaked intrusion. As she stands before him, the protagonist is struck by a stark realization: the girl he once knew as a simple playmate has changed significantly since they last spent time together. Most notably, her figure has matured considerably, drawing his attention to physical developments that were entirely absent during their childhood days. This unexpected transformation forces him to confront the fact that their relationship can no longer be viewed through the innocent lens of the past. Now, faced with a thoroughly soaked and visibly grown-up childhood friend standing right inside his home, he must navigate the awkward tension and shifting dynamics of their reunion.
