"Kiss me. Prove to me that you don't love Tsukushi anymore. When you're with me, you're always thinking about something else. I'm your girlfriend. It's rude to make me feel so uncertain. If she means nothing to you, you can kiss me, can't you?"
Tsukushi Makino tells Sojiro Nishikado and Akira Mimasaka about Tsukasa Domyoji asking Shigeru Okawahara to go out with him. The two guys are stunned trying to imagine Tsukasa doing that. Tsukushi says "You should be happy for him," leading Sojiro to question "Wasn't it a shock to you?" Kazuya Aoike then arrives to eat lunch. Tsukasa walks up casually minutes later. He confirms that he is dating Shigeru when Kazuya asks. Tsukushi congratulates him, to which he says "I don't want to hear that from you."
That afternoon, Shigeru chases after Tsukasa since he walks too fast. He snaps at her, which causes her to start crying. She declares "This isn't a date." Feeling guilty, Tsukasa asks "What should I do?" She grabs his arm and orders him to "match her stride." Shigeru then asks him when she can expect him to love her back. He answers "In time." Meanwhile, Kaede Domyoji gets a report from Nishida. When she asks about Tsukushi, he tells her "She doesn't seem to be seeing Tsukasa outside of school, but..."
Shigeru bursts into Tsukushi's home and joins the family for dinner. Afterwards, Shigeru talks to her about Tsukasa. In her head, Tsukushi laments being "forced to listen to this." Shigeru wonders if Tsukasa still likes Tsukushi, who then gives her words in encouragement. Later, Tsukushi tells Rui Hanazawa about Shigeru coming to visit her. They happen to overhear Shigeru and Tsukasa arguing below them. She orders Tsukasa to kiss her since she is feeling "insecure." He does so as Tsukushi looks on in shock.
