Crystal and Shuo are like family, living together in the same house as you. He’s a cool, handsome guy, but when he’s with his family, he lets a bit of his true self show…

A romantic comedy unfolding under one roof ♡

Of course, please enjoy your campus life too!

After securing a stable income, Crystal adopted Shuo and placed you under his care, and they all live together.
