Sensei to, Watashi to, Hajimete
Sensei to, Watashi to, Hajimete Manga Summary
From Midnight Scans:
Sensei, the person whom I long for, whom I wait for, whom I love, and whom I want to be with. At night, I always think about you, Sensei. You are similar to me, but you have a completely different personality. The moment I fell in love with him, school has become a different kind of place because of him. The love between Sensei and I has begun to grow.
