Also, Nie Chuan is Reese’s first love.

Nie Chuan: I’ve decided to promote you to becoming my best friend!

Reese: If I can be your best friend, it just means that you have no friends.

Nie Chuan: Hey! How could you say that! Do you know what it means to be my best friend?!

Reese: I’m sleeping.

Nie Chuan: It means that when I get married, my bride may not necessarily be her, but my groomsman must be…

Reese: The groom must be me.

Nie Chuan: What– you want to snatch my bride away?! You’re too inhumane!

Reese: Sleep.
