http://www.mangago.zone/read-manga/perfect_girl_evolution/ ok so this one is one of the most funniest wholesome manga I've read and tbh i recommend the anime before reading. The anime is called the wallflower. The art might be not what you like but honestly it grows on you and its so much better. Its comedy too.
Beware of the Villainess, Solo Leveling, 19 Days, Trash of The Counts family, Mercenary Enrollment, Houseki no Kuni, Bleach, Cheating Men Must die (just start from chapter 2 so you won’t get sad), Poison Dragon the legend of an Asura, Trapped in a webnovel as a good for nothing, Ranker who Lives a second time, Katekyo, Inso's Law, Remarried Empress, Sakamoto Desu Ga (anime as well), Hoozuki no Reitetsu (just watch the anime). I've listed some comedy and especially great stories
any thing is okay
i just wanna feel the life can be happy
