Tang Chi×Chen Lan
Shirakiri's obedient and probing younger brother dressed in black × his hard-tongued, soft-hearted, sober and sinking older sister
Tang Chi called Chen Lan "sister" for eighteen years, until his parents died "accidentally".
The police said it was an accident, but Chen Lan didn't believe it, and neither did Tang Chi.
During the pursuit, they all wanted to leave each other in a safe place and move forward alone.
"Tang Chi, don't you even listen to your sister? Come back."
"Sister?" Tang Chi held her chin with one hand, whispered into her ear, "Are you?"
He goes deep into the darkness, his hands are dirty, but his sun comes to him.
They are siblings, they are not related by blood, and they are lovers who should not be together.
