Houkago, Sensei to Koi ni Ochiru

Nozomi lied about her age and is working part time. She was in an extreme bind when she was seen by Sawamura Sensei! But sensei permitted Nozomi to work there. This is the beginning of a secret relation with sensei. When Nozomi is with sensei her heart beats faster. Is this sensation… what you call love? But is the reason why sensei is so nice to her because she's his student?
