[Mutual healing / devoted to each other / secretly in love with each other]
(Delicate, frail little streamer vs. gentle, thoughtful big brother)
“Yandere” is meant literally here: Lin Mu is a sickly, delicate little darling.
When he was six, Lin Mu was kidnapped, leaving him with psychological scars. After he was rescued and brought home, he fell seriously ill. When he woke up, he couldn't remember what had happened and was unable to communicate normally with strangers.
From then on, the Lin family began hiding Lin Mu's existence, hoping to keep more people from learning about him and disturbing him.
After Gu Feng was rescued at the age of ten, he kept searching for the younger boy who had been with him, but could never find a single clue.
What circumstances will bring them together again years later?
