As a child:
Brother: Brother, other children have their brothers to play with.
Brother: Oh.
…
Brother: Brother, other brothers will help my brother with his homework.
Brother: Oh.
…
Brother: Brother, other things...
Brother: Stop, let's talk about it, how about you become my brother from today on? Okay bro
After growing up:
Brother: I'm your fucking brother.
Brother: Shh. Honey, call me brother again, I still want to hear you.
Brother: ... Damn, this brother shouldn't stay for a long time.
Intention: Love is not a casual promise. Okay, I don't want to say any more (I really like this lyrics)
