A Dangerous Man, Maity's Sweet Temptation (E15)

Lisa declares that she will celebrate her love with Mighty-sensei. But in her heart, she still hadn't fully given up on Ōtani. Mighty gently consoles the grief-stricken Lisa and she cries into his chest. Seeing this, Ōtani freezes in his tracks. After classes are over, Ōtani and Mighty meet, as he's become the substitue advisor for the basketball team. Mighty muses that he might take Lisa for himself. Ōtani blurts out that he doesn't like Koizumit that way at all. Of course Lisa overhears this, and the chasm between her and Ōtani widens yet again. (Crunchyroll)
