Like when he tricked the system by dressing up ass a girl to get confessed too

So we know pretty early on that she is the younger sister of the hero so we can guess she has talent but it quickly get out of hand. She has so much plot armor in the form of talent that I feel like I haven't seen this thick armor even with MCs with lazy writing.

Like she is insanely good in fighting but it makes sense because she is a hard worker.

She has sooo many talents that academy only showed few of them and those talent are so OP that a single talent like that can only appear in once a thousand chance (a speculation). It clearly shows how much of a cheat it is after seeing the price of a single talent in MCs shop.

She can learn anything, she can wield any weapon without much effort, she can learn fighting skills that others take years or lifetime in matter of months.

As for the reason, she is talented.

It is hinted that she can't cook. Oh so it means there is something she can't do... NOO. she learned and got so better at cooking in just a semester that she can get sky high praises from dukes daughters who has only eaten best. As for the reason for her such skill growth? yeah it's talent.

She is so good in studies that she can beat anyone in exams without even a little studying. The reason? yeah talent.

She looks a little slow or dumb but she is insanely sharp and intelligent that she can solve the 5 days group exam problem in matter of hours that even smartest person with the studying talent related to intelligent couldn't. You can't guess the reason for that.... it was talent.

MC says that she is not good in interpersonal relations but I never felt like that, at least she is a thousand time better than our so called middle aged MC who doesn't show a speck of wisdom that comes naturally with age nor he knows how relationship works except at the start of story. he just shows unnecessary jealousy and guilt sometimes and many times respectively. She is so much better at analyzing, planning, leading and every other little thing a adventure needs without ever going on one before. the reason is TALENT.

MC gets a talent but he can only use that talent properly in the future,

he gets a second talent but that's also for the future, he gets/copies? a skill but that's wont help much now either. Then he copies a skill from overpowered ellen, that means that he can now increase his growth speed? f*king Nooo, he can only keep up the previous speed because growth should slow down after initial stages AND ellen is an exception who can still grow at a dozen times faster speed even after surpassing 4th or 5th year students in strength in her 1st year. BuT what is the reason?? SURPRISE SURPRISE it's talent.

Then he gets his 3rd talent and even gets additional benefit that can make him strong but What happens? That can only work in the fk ing future.

He actually keeps getting stronger steadily but it felt like a crawling speed. Author tried so hard to keep ellen an OP character and so she can keep up or even stay ahead of MC even in end stages that he completely and utterly destroyed the idea that there was a reason for every little thing. This can be interfered with the secene where it is explained why students couldn't use swimming pool in winters. It is clear that author kept his bllsht of giving plot armor to ellen so she can stay ahead of MC even tho he has a op cheat.

I felt like if I ever met author I would hung him upsidedown down and tickle him to death for writing such sht development even tho he was so good at writing and there was really no need to try so hard on ellen. She could have kept up with MC in strength without so much bllsht.

(The MC and Ellen reconciled, that what I understood from the last chapters of the epilogue but the process was not mentioned for anyone to verified that)

in chapter 46 of the manhwa there is a different form the same events in novel, they skipped the part of the story in novel where Charlotte finds a blond hair that belong to the MC in Eleris bedroom and Eleris respond that it's her boyfriend hair, and they also skipped the part where Charlotte tell to MC that Eleris is suspicious that part of the novel happened after they left Eleris shop. In the manhwa however it's been done as they are in the Eleris's bedroom.

now if I recall correctly the when Charlotte and Ellen start to investigate what pointed to our MC identity to be the demon lord was the fact there was blond hair in Eleris bedroom before the need for our MC to come and go to deliver letters between Charlotte and the boy.

what I want to say after all this that maybe the unfold of our MC identity reveal might be different, there the Black Order who can still pull the strings for the Heroines to revel MC Identity or Bertus is the one will reveal MC identity or maybe with what already happened in manhwa is enough point to our MC identity by the Heroines

the son of the demon king, a prince to a deposed nation and he's terrified.
