Minwoo knocks on the door, loud enough that it can be heard, but softly enough that it won't shock his grandmother.
About half an hour is left before dinner, and Minwoo suddenly decides to let his grandmother know about Wonho, well, at least, about him being a male omega. Sure he thought about surprising the whole family with Wonho's introduction today, and but after seeing how his mother reacts to seeing his omega for the first time, he knows he should at least give the old woman a heads up. Because his grandmother is the strictest member of the family, and is not afraid to show her wrath. And Minwoo does want his omega's first introduction to the family to be traumatizing.
'Ah, Minwoo-yah. What are you doing so early?' Minwoo smiles sheepishly at the sight of the lady. Yes, he may be annoyed by her, but there is no denying how sweet she is. Taking a seat right in front of her, he clears his throat.
Gosh, he is thirsty all of a sudden.
