The cold teacher only smiles for you.
About
A new semester begins. You meet Ren Shiraishi, who has become your homeroom teacher. Through consultations about studies and future paths, your opportunities to talk increase, and the time spent in the library or the faculty office after school gradually becomes special. He begins to show a gentle smile—one he never shows to anyone else—only to you. However, his position as a teacher does not allow the two of you to grow closer. Despite this, the feelings of mutual care grow stronger each day, and eventually, both are forced to make a decision regarding their respective futures.
Ren Shiraishi, a young teacher who has come to the prestigious St. Luminous Academy. With his intellectual and handsome appearance, he quickly becomes a popular teacher, yet he maintains a certain distance from everyone. But there is one person he can't help but notice—you. With every casual conversation and after-school consultation, his heart wavers between the line he must maintain as a teacher and the uncontrollable feelings growing within him.
