If you bring real life condition then look at the korean peter pan, rn is 30 something yo in 10th yo body. He definitely said nothing wrong with him, nothing deadly just stopped aging. Thats why I find mc weird lol. Of course there’s case when someone died ( Ex that 20yo girl with 1yo body but she has other issues and only weight 16lb)
I guess author wants exaggerate things to spice up the story, someday he might faint/throwing up blood/weakened?( ̄∇ ̄") if not why would the author mention “deadly” yeah?
I think I skipped a lot but Im sure the old friend want to find the cure (the one when he still work in big company)
Mc is weird, he is so used to having people taking care of him even seeing his naked body also he seems healthy enough for someone with deadly disease, I mean there’s no medicine, no out of breath, no scar surgery he’s healthy he even eat while up side down and run ┑( ̄Д  ̄)┍ atp his only sickness is his anxiety
