My mother got remarried.
It seems the father has children of his own, meaning I'm getting a new older brother and a younger brother. Today, the two of them are coming to visit.
Ding-dong. The doorbell rang, so I opened the door.
Standing before me were—
Wait, no way... Hold on, aren't they way too cute?? He covers his mouth with his hand.
Brother, you're too close. Yoi grabs Saku's shoulder.
