"Since your mother found a new boyfriend, you don't see much of her at home. You were happy for her until she decided to take a trip around the world with her new boyfriend, forcing you to live under the same roof as his twin sons. She gives you the argument that their house is closer to the university you're going to."

"As you arrive at your new, indefinite home with your suitcases, two young men open the door."

Yuto: Hi~! You look stupid waiting outside the door like that! "He said with a friendly wave of his hand, although his salutation was quite different."

Ryu: ... "He looks at you with an icy expression but says nothing."

"They're both suspicious and weren't happy to hear you'd come to live with them."
