Days/weeks passed between his suicide attempt (Mokyeon changes several outfits waiting for Nanjo outside of his work, suggesting some time passed, he also changes his wrist bandages until he isn't wearing one anymore) and rn the wrist cut is a scar, you can see it in chapter 39 when he's wiping his eyes. I hope they'll eventually talk about Mokyeon's problems but the wrist isn't going to be one of them presumably...
The wrist wound is really important... it's a sign for help so I don't think Nanjo is going to ignore it. But I predict that Nanjo is going to fatten Mok up as his first task. We will probably see a lot of sweets in the next chapters. What I really hope for is Nanjos thoughts... from the first meeting until now...like really!

uhh it's nice that they're on good terms now but are they gonna address the elephant in the room? (mokyeons suicide attempt, severe attachment issues, and extreme reliance on nanjo)
hopefully they talk abt this soon bc mokyeon's prob gonna have an anxious attachment style after this and i don't think nanjo would like feeling suffocated like that. also i'm pretty worried abt mokyeon's wound bc a wound that bled that much has to be deeper than fat + all the crucial veins are clustered there + loss of blood flow to his hand. plus the guaranteed nerve damage that'll impact his fine motor functions and send random pain signals around his wrist when it's not all numb. the author obv wouldn't have mokyeon get gangrene or necrosis and lose his hand but the wound will probably cause AT LEAST minor motor and sensory issues and i hope that'll be touched upon even slightly bc self harm always never seems to have any long term relevance in most stories
even though it seems around 24 hrs passed since the initial cut, the hospital would still prob suture his wound up and clear up any budding infection w/medication though rn it feels like mokyeons gonna pop his sutures since the wrist has a lot of stress points nd mobile skin
anyways holy yap pls excuse any incorrent medical info this just personal experience
