Jiang Cheng runs to the nearest bathroom and looks in the mirror.
He looks... okay. He's still not Lan Wangji, who if the magic thing doesn't pan out could take up a second career as an idol, but he looks serviceable. It is possible, maybe, to imagine that someone might want to kiss him.
Apparently he has good cheekbones. He looks at them suspiciously. He's never thought of any part of his body as being good before. Mostly they range between "bad" and "barely acceptable."
Without thinking about it he turns on the water and angrily splashes it onto his face. He scrubs until all the concealer is off.
The face in the mirror is more familiar. He'd say it was a face only a mother could love but, well.
He goes back into his room and shoves the concealer underneath his mattress and closes his eyes and pretends to himself that he's not thinking about it.
