I think Taeyeon should've sung with Jonghyun like she usually does for Breath because Chen's vocals overpower hers so they don't really harmonize well. Also can you guys comment on the performance instead of how jealous Baekhyun would be, considering it's hard to believe they even exist as a couple, let alone be jealous of his band mate for singing. Anyway it'll be a longgg time until SM lets Baekyeon sing together because even now, a lot of EXO-L still hate the whole dating thing.
