I literally stopped reading for a full minute after the hair-drying scene. Just sat there. Let me explain why.
"Gu Yu continued drying her hair, but his movements slowed. Not because he was afraid of hurting her, but because he feared losing control."
THAT LINE. That is the entire romance of this book condensed into one sentence. This man has been described since childhood as emotionally muted — nothing stirs him, nothing moves him. And yet here he is, towel in hand, watching a girl with wet hair and flushed cheeks, and his heartbeat is RACING. He almost can't resist cradling her. He almost kisses her neck. And when that fleeting warmth actually touches her skin, he reacts "as if scalded" — abrupt, hurried, flustered. The man who doesn't fluster is FLUSTERED.
And Yan Zhao? She feels it too. "The moment the towel touched her hair, Gu Yu's fingers, separated by the fabric, gently pressed against the nape of her neck. The warmth from his palm seeped through her skin, making it impossible to escape." She's breathless. Her ears are burning. She's frozen. And then later, lying in that narrow bed in the dark, she keeps remembering it — "that touch was like a spark gently ignited in the darkness."
They're both feeling it. Both pretending they're not. And the bed scene — the distance between them that's "neither too far nor close" — I can't. The restraint is EVERYTHING.
