Tetsu and Senou as a couple despite all that disgraceful behaviour is quite upsetting. I would like it more if Tetsu ended with Tomoki. He's such a good guy. On the other hand, Tomoki dealing with an unrequited love and later getting targeted by Sahara-sensei is pretty funny. Playing the role of the though teacher just to accept that he's in love... Well.
I just have to say that Yasunori is the best father ever, what an hilarious character.
