Kininaru Ano Ko

From Starry Sky Scans:

Due to their student-teacher relationship, high school student Wakino’s confession was rejected by Yukari-sensei. Wakino promises he will confess again after graduating. However, being full bloom in puberty, every day Wakino finds their platonic relationship harder to endure. One day, Wakino mindlessly zeroes in on Yukari-sensei. Will this lead to utter rejection…?

One shot:
"Ame Otoko" - "The Rain man"
"It's Tuesday and raining. So that means he's going to be there for sure.......since he's the rain man"
Every Tuesday it rains and every Tuesday, Koizumi-san stops to listen to a young guitarist on the way home. He can't help but feel attracted towards him. A song that makes you feel alive....a man who yearns for true love.....
A really sweet 50 page oneshot that leaves you with a warm feeling within.
