Forgotten Title Leveling novel

I'm looking for this leveling novel which makes the MC follow the OPM training regime while not balding in the end. I saw it as a webtoon in mangadex so yeah...

edit: it's called Solo Leveling on mangadex.
ok so basically premise is world has dungeons. MC is weak and poor with an ill mom. He almost dies in this dungeon then becomes OP cos of OPM training. With a story like that, i was 99.9% sure the webtoon was adapted from a webnovel.

 

Literally any OPM fanfic with OC instead of Saitama... Especially crossovers like OPM X SAO or simillar gaming worlds.

My bad thought it "Recomendation" tag

 

NEET dating system, something like that

 

Definitely not NEET

 

I don't know what the novel is but I'm just gonna leave this here, since I'm intrigued and want to read it.

 

Pretty sure it is Starchild Escapes Arranged Marriage.

 

i want this to be the title so bad ugh it's so good
