Hiatari Ryoukou!

The story focuses on the relationships of Kasumi Kishimoto, a high school student. When she enters Myōjō High School, she moves into her aunt's boarding house, where four boys attending the high school are tenants. Despite her steadfast determination to stay loyal to her boyfriend, who is studying abroad, Kasumi finds herself slowly falling in love with one of the boarders, Yūsaku.

The game does not have you playing the protagonist from the anime, but an original male character staying at the same boarding house and interacting with those characters as friends.
