I actually find Lan Wangji pretty uninteresting as a love interest, too ;) It's one of those archetypes where I go "aww, he's pining!" while reading but if I had to deal with such a person in meatspace I would tell them to get the words out or get lost! The saving grace for Lan Wangji, for me, is that he saved A-Yuan/Lan Sizhui. My heart melted when Wen Ning recognized him ;__;
