Married with Brother In Law

I love this novel, it's simple but good. Man hunts, man happy. Sometimes authors try too hard to make stuff complicated and poetic for no reason. Hopefully the author will get better soon!

Ankoku Kishi Monogatari ~Yuusha wo Taosu Tameni Maou ni Shoukansaremashita~, this ismy recomendation for you, just give a try

He is an overpowered classic mc who is underestimated constantly. He knows ki and all the ancient chinise medicine technices and proves to the rest of the world that chinise magic is real and more doctors should learn it. While also cultivating his ki to become strong enough to heal his dying master.

this better not be sad, (the wallpaper reminds me of amnesia

that is just how the novels world works, blessings make you stronger and that puts the mages at a disadvantage
