True. It's still unclear. But that's still amazing to me that he was able to smile. _ Hyeon doesn't seem to buy it neither. ? Wait ans see. CherryTree
That's why I'm so worried... He wasn't able to fake a smile before, but we know he's not happy and he still did it now. It feels like he's becoming even more detached. But, yeah, hopefully we will get some clarity in the next chapter.
A smile is not always an indication of good things. I feel like he is taking steps to resolve relationships before making a very bad choice.
