Kenji woke up the next day and did chores practically all day long, except for mid-afternoon, he went to the sweets shop to talk to K-san. He enjoyed talking to her, since she seemed to be the only one interested in him, but then heard a bit of gossip from her that probably should've been kept secret. She told him that his sister was having a date with Ichihara. Kenji just froze for a moment and asked her to repeat it, and so then he went straight home, not even buying any sweets that time. It was weird for him to come home without sweets to munch on, but when he got home, he just went to go sit in the livingroom and watch tv.
Their parents called a few minutes before she came home, saying that the thunderstorm flooded the streets and they will be back either late at night or tomorrow morning, due to all the routes to their home being closed. When he heard his sister shouting, he went to go greet her, and noticed she was completely soaked. "Sis, you're soaked, where were you?" He asked, more worried rather than furious.
In all honesty, he wasn't angry or furious at his sister for going out with Ichihara, he was just upset because of the books that he read and how him and his sister were possibly lovers in their past. "Come on, we gotta get you out of those clothes and get you to take a nice bath." He said strictly and took her hand after she took of her shoes, leading her towards the bathroom. "I'm gonna make sure you're thoroughly clean as well." He said to her and closed the door to the bathroom once they were inside.
