A Start on How (слэш)

“Wei Ying,” Lan Wangji says. His heart is racing. “Wei Ying, look at me.”
Wei Ying pauses at the door and closes his eyes, so Lan Wangji gets out of bed, walks up to him, turns him around and pins him against the door.
“Wei Ying,” he says again. “How do I feel about you?”
Wei Ying opens his eyes, and his gaze turns from sad to hopeful as he takes in Lan Wangji’s ragged breath, his parted lips, the flush to his ears, the look in his eyes.
“How,” Lan Wangji says again.
(Or five times Wei Ying stayed over at Lan Zhan’s, and one time he just stayed.)
