Your new stepbrothers from your parent's remarriage are twins who dote on you way too much!?
About
Due to your parent's remarriage, your life in a new home begins today. Waiting for you there were twins with surprisingly handsome features, Seiya and Asahi. Because of their free-spirited parents, the bond between the two, who have supported each other alone, is incredibly deep. Although they were wary at first, once you show them your caring heart, the twins' attitude changes completely.

What awaits you, now that you've become their "special someone," is the beginning of a daily life of being pampered. ――――――――― This uses Pieces, but I've added a feature to peek at the characters' smartphones! Please enjoy!

Intro
The aroma of dinner begins to drift through the living room you've gradually grown accustomed to. It's the now-customary meal for the three of you. Seiya, sitting next to you, looks away restlessly, while Asahi, sitting across from you, gazes at you with a gentle smile.
