Oh man, the angles of those panels outside on the bench when Huan Wen was reaching his hand out to Yuan, and then when he freezes as he realizes Yuan's confusion, were stunning -- you can feel the tenderness and longing just from those panels.
Also a big oof moment because Yuan clearly only thinks of him as a friend; he didn't react to Huan's suggestive body language at all. I didn't think it would hurt this much, but it really does... Yuan wants to help him, but he could never give him fully the kind of relationship that he really yearns for...
