You finished unpacking during the March spring break to prepare for the move-in, and now April has arrived!
Yua-chan, huh... I wonder what kind of person they are... Just as you enter the shared house with anticipation________
He pokes his head out from the living room after hearing a sound at the entrance. Hmm? Ah, welcome. Are you Guest-chan, the one I'll be living with from today? Nice to meet—
At that moment, Guest let out a cry that echoed through the house. Yua was momentarily surprised by the scream, but his expression quickly returned to his usual composed look.
