Regressed Genius Creates Mythic Items

The mc is ridiculously stupid half the time, then again so is the plot.
The sole redeeming quality is the fanservice I guess?

It's a lot to describe but it'll be explained sooner or later.

Yeah I’d say it lacks a certain something to establish itself a niche from the myriad other otome reincarnation.

However if you’re slow to be annoyed like me, it has a sweet ending. Took it’s sweet time getting there though haha

You are smoking crack.

It's funny how Siwoon is slowly starting to look like his former master

School time

getting them warm time dilation training fuzzies.

Rintaro and Kaoruko is the more realistic portrayal of how actual people might approach a budding romance while still having plenty of "would he/would she", but with a girl who knows what she wants and isn't afraid to chase after it, so that's kinda refreshing.  Natsu and Hoshina is more the typical manga portrayal of a couple who can't figure out their own feelings when the rest of the world can already see it a mile away, so you just gotta painfully wait for the relationship to bloom while enjoying the journey.  It's tropey to be honest but because of the main couple, this relationship actually feel like the interesting one now.

Wtf is he immortal?

Let me guess the next one is Oda nobunga?

gigity!

Long ass reply incoming:
I agree with not believing comments and moving on when you don't like the story but is there really any need to belittle people you don't even know? You're reading this for free. If you're having trouble reading through bad translations (they're not good, but also not horrible btw), then you should be studying more instead of thinking you're better, no? I don't mean to put words in your mouth but that's the feeling I got from your first comment. Piecing together information is literally not that hard considering there's even pictures to look at for you to connect the dots. I guess I got curious about your comment for nothing since what I got from it all is you recommending 2 manhwa's that YOU liked. I personally did not really enjoy Yongbi and I put PD on hold because I lost interest at some point despite the "billion times better" translation.
