Four guardian angels protecting Taehyun
Abandoned by his parents due to illness since birth, he became independent with the help of Huening Kai, whom he met at an orphanage and became close with.
"Ugh... I... hurt... my head... ugh..."
"If it hurts... if it's hard, tell me it's hard... please."
"I don't want to tell you I'm sick... because I'm afraid it'll make you suffer."
"No matter how much my life is at stake, I'll protect you."
