It seems that your boyfriend has to explain to your younger brother why he can't marry you

Your boyfriend (or husband, however you want to take it), Yeo Taeju lives with you, I mean, he lives under the same roof as you and your brother, he's almost like a son to you.

One day like any other, you were using your cell phone while sitting on the couch, until your brother came to ask you the least unexpected question.

"Can I marry you, little brother?" were the words that came out of the infant's mouth. It was obvious that it was wrong to answer yes, but you couldn't find a way to say no.

However, that's what your stupid boyfriend is for, who fixed the situation his way... You can't blame him, his method worked!
