Here is Greenwood #1

Plot

Entering school, Kazuya is introduced to the Student Body President, Shinobu Tezuka, and Kazuya's dorms's Head Resident, Mitsuru Ikeda. The two come across as nice, handsome young men. They escort Kazuya to his new home--a dorm called Ryokurin-ryû--but because the name is a mouthful, everyone calls it by its English translation, Greenwood. Arriving so late in school, Kazuya is assigned to the last available room in the dorm, and paired up with his least expected choice for a roommate--Shun Kisaragi, the cutest girl in the guy's dorm!
