Oh... thank you so much for the comment, THIS is why I love spoilers. I was about to read full of excitement thinking this was a fantasy academy story with an older teacher mc and students that AREN'T sexualized love interests :(((
I love it when the main character has students/disciples but it's so rare for the relationship to be completely platonic
You may have read this but these are my favorite manhwas with this set up where the mc isn't weird.

I love action, I love transmigration and reincarnation, you'll find me in the comment section of many from these genre from slop to peak, a subgenre of this comment section you won't find me in...is harem.
I see the patterns, firstly the hero party....they have many daughters? Really? What a coincidence.
Secondly the ratio of male important characters to female characters is suspicious.
Thirdly aren't these girls teens? What's with the awful proportions emphasizing their chests? I'm not saying there's no teenage girls with big chests but come on now.
It's not giving father figure, instructor manhwa instead giving multiple women fall in love with this character for no reason harem slop, and I'm not the target audience.
Leaving this comment for someone like me, so that they don't waste their time reading the chapters like I did.
