Does She Like This Guy, Is It Her Ex?

M1, T3: The tall handsome guy who suddenly embraced Lisa was an old childhood friend of hers, Fukagawa Haruka. It's Valentine's Day. Lisa can't decide if she wants to give Ōtani chocolates. Ōtani dismissively says that he'd take politeness chocolates. While she puts on a defiant front, Lisa's actually happy. Haruka then makes his appearance and gets in a fight with his love rival, Ōtani. Ōtani comes to the irritating realization that Lisa and Haruka look good together just standing there, and even rejects Lisa's chocolate. That chocolate then ends up with Haruka. The next day, Lisa apologizes to Ōtani who's looking all depressed. They both quip that it was just politeness chocolate, and they end up getting a little closer.
