Maybe he went to his grandparents home? I used to sleep at mine house when my cousin was there so we could have big fun. Quite normal thing for me, also it is important to socialise even small children
Oh nice Theory
My sister baby stay with us when they are tired from time to time, when you have a big family grandparents tend to babysit a lot. My nephew as 3 sets of gramps he lucky
causeee couples need time for themselves. and everyone dotes on byul so naturally he'd have to spend some time in the park main house
Hye-sung said he was jealous of the pretty omega. He then found what he assumes is porn that Dojin was presumably watching & is about to watch it. My guess is it’s to find out what kind of ‘sexy stuff’ Dojin us into. But of course Dojin will misunderstand & get annoyed & interrupt. He’ll probably cause a big fight.
Anyway, why wouldn’t Byul be home that night if both parents will be?? He ain’t old enough to be having sleepovers...
