Student Uke figures his maths teacher is gay because the man keeps gazing at a particular male student, then Uke blurts his thoughts out loud one day. Teacher Seme asks Uke if he's spread any rumours already and Uke replies by saying he himself is gay, so he won't. Uke starts spending more time with Seme in the maths prep room and they become closer, they fall in love slowly. The subtle sweetness and insecurities of falling in love are a really lovely read.
When they eventually confess Seme asks Uke to wait a little while, till he's graduated, as Seme is very strongly against dating a student.
