Mystari's manga / #Tsundere Seme(3)

High school student Ao decides he’s in love with Ryoumei-san, a priest at the local shrine and Ao’s childhood friend. Not one to beat around the bush, Ao immediately tells Ryoumei he wants to do perverted things together, but it will take more than a little persuading to get the shocked Ryoumei into bed. Between bad advice, romantic rivals, and Ryoumei’s scruples, there are many obstacles in the path of true love.

A mean-spirited senpai and the young co-worker he loves to bully. But this grumpy guy has a cute side to him, and the clumsy kouhai isn't as much of a pushover as he appears.
