It was because the guy who was competing with Mu for the scholarship told everyone that Mu got it because of his connections or something like that and in the earlier chapters, it was mentioned that Mu used a shower gel with strong smell and the seme did not like it. That's y he distanced himself.
i think it’s just his personality, standoff-ish
All I remember what abt his scent
Thanks for the explanation. I definitely missed on those details.
I wonder why Yuanxun was cold to Mu in the first place. It was unexplained. Cold for no reason at all (unless I missed something). Was he just being too prideful because an underclassman was trying to get to know him? Idk
