Nah, the last panel is a smirk,and not in a good way smirk,no he isn't warming up to his tears,he likes him back you could actually tell from some hints in season one,so he was surprised to know mk likes him,mk used to call their relationship temporary, just for fun and such things, that's why he was surprised

I feel like Nanjo is weak to Mohkyeon’s tears and he has already started to warm up to MH. The last panel shows him with a teasing face rather than serious tone, too. Alsoo, why call MH again and meet up with after knowing he was with Sunhwa? I smell jealousy or worry that something might happen between the two similar to s1. Hmm
