After work, he returns home and his sister informs him that her friend is here. Ryō is surprised to see that it's the girl from earlier and introduces himself. As his sister goes to talk with their mom on the phone, Ryō wants to thank Ichika Arima, but considers buying her clothes or shoes is too cheap and offers a kiss. Ichika is immediately disgusted and expresses it, however Ryō finds her reaction as wonderful.

For a week, he uses his sister Rio Amakusa to deliver chocolate and other presents to Ichika, but as he wants to send a rose, she gets annoyed and gives Ichika's address. That evening, Ichika calls him and he immediately recognizes her from her voice. He wonders if she likes roses and if the color was okay, and Ichika states that's fine, but she feels a bit bothered by him. However Ryō explains he will continue as he can't stop his feelings for her and she is free to insult him and get angry at him for the things he will do. Ichika gets angry and tells him to not send any more flowers and hangs up. Ryō saves her phone number and then next day, he still sends her a flower.
