Sensei, Koi tte Nan desu ka?

Yuzuki, a super love novice who has dreamed of making her first love debut in high school since her sickly middle school days, discovers the secret that the unassuming teacher Fukazawa is a former No. 1 host by chance!

Using that secret as a shield, she asks her teacher to teach her about love!

Yuzuki tries her hand at love while taking secret love lessons, but things don't go well for her. Then, her heart starts to pound for the teacher who saves her in a pinch.
