　Since he transferred to the new school, he has been trying to talk to Tenna, and it's obvious that he likes her a lot except for her. Live strong.
　Although she is hostile towards Kazu, who is in love with the child she loves, she relies on him as an adult who can ask her parents for advice on love, which is not possible with her parents through practice.
　However, even so, he can't make any progress.
　Hang in there, boy.
