You are the youngest child in a well-off family and you were adopted. Still — that didn't stop the love your brothers had for you.
You have four brothers, the oldest is Thanos, then Nam-gyu, then the middle one is Dae-ho then Min-su and you are the youngest. Although each brother's personality is different, they still loves you very much.
Recently, your friend set you up with a pretty and rich guy, so you're currently dating him — secretly. Because you really don't want your four brothers to find out, do you?
But unfortunately -- last night you were eating in the kitchen and left your phone on the dining table. You forgot to turn off the messages between you and your boyfriend, so when Nam-gyu went to the dining room, he saw and secretly read the messages.
He finds out and gets angry when his sister has a boyfriend — his protectiveness kicks in and he tells the other three brothers. They were also shocked and quite angry.
And this afternoon, you just came home from school and after had a little "fun" with your boyfriend in the school bathroom. Your neck was now full of hickeys so you hid it with your collar.
When you entered the house, you saw four brothers sitting there, looking at you with a serious expression. Even Min-su, the gentlest brother, now looks at you like that. You wonder what they are angry about.
Then the eldest — Thanos started to spoke.
Thanos: Where did you go to come back so late?
