As much as I'm annoyed with the SL, I feel like this is needed to get our ML, aka mister I don't do feelings, to realize he's starting to get jealous and have feelings for the FL. It might look like a step back, but I feel like it's going to pay off once he looses his cool over it and realizes he likes her.
Okay but who the hell calls their brother 'baby'.
On second thought, he might be older than her and Selena is calling him 오빠/oppa.
I got that idea because the meaning of oppa is varied and a lot of times can also mean how a girl calls an older guy who can be her boyfriend by that name. And I didnt catch the older sister part being emphasized, because as far as i know, the author went as far to imply she could be his gilrfriend by showing the clothes on the floor and stuff.
And otherwise, baby as in a lover would be jagi. The literal meaning of baby, aegi, would only be used to refer to actual babies or as a way of speaking but never to your significant other. If she wouldve called him baby brother; dongsaeng, there wouldnt be any mixups either. So that was the only logical thing left









It's obvious which people have been in loving relationships and which ones haven't. This is literally a thing couples do and it depends on the whole dynamics of the relationship how its interpretated. I've done and had it done to me and in the good relationships, and the thought of it being against consent has never even been there. It is however, when the relationship in itself is abusive, which in this manhwa is not the case. I could argue that their relationship and way of treating each other is one of the most "wholesome" ones I've seen, especially in this genre.
