There is sudden plot out of no where, a supporting females that pop up randomly, and fell in love with mc.
He want peaceful life but keep making decision that will messed up his peaceful life without thinking, like not disguising, being impulsive.
I mean, he put wooden sign that he will treat any sickness?? why he doesn't search healer clinic and work there ? why in the middle of street?? and some random noble woman ask for his help!
He seems really confident with his operation when he never done that in the new world, what if the new world rejecting him as a cult? what if the body there can't take operation?
He doesn't want to be saint, but he didn't disguise himself? not running away? doesn't tell his parent / consulting about the saint thing! he already knew his parent doesn't want academy take him! yet he witheld info that might seperate him and his family.
It feels a bit iffy, he decide on his own to treat comatose patient, when he was rejeced by 'elf relatives'.
He secretly went into patient's house, in the end he decided to use heal when his mana might make the elf died like the deer situation, but he decided to gamble.
What if the elf died? nope! the plot armor is there.
There is suddenly romance that bloom between him and elf, which is romance between doctor and patient? too rushed, forced and so random.
In the end he decided to randomly become a saint to go to Holy Empire to learn new diseases or how to treat someone..
He doesn't bother searching info about where he should learn, buy book or something..
What if in the Holy Empire there is only God Bible?? no diseases book?
It feels MC doesn't think much, random forced plot, forced plot armor, forced romance, also harem vibe (where there is only woman that reach out to him).
The only thing I like is his supportive parent.
