Waiting in the Summer: Senpai Was Amazing

Things turn awkward the next day, but they try to put it behind them. More complications arrive when Manami, Tetsurō's married sister, takes a homebound Kaito for shopping. Ichika sees them, and followed them via teleportation with Rinon's help, even at her place. Worried about what will happen next, Ichika enters and tries to take him home...though not without clashing a bit with Manami, acting like an overprotective lover, until Tetsurō comes to clear things up, that Manami is already married, and she's here because of a petty quarrel with her husband. As an apology Ichika asked Kaito for a favor from him. He asked if she could help him review for the finals, to which she agreed, and helped him study until the final day of exams.
