MC initially has to restrain his spatial perception ability and lacks the ability to see anything but the outline of objects with his spatial perception as more info is too overwhelming. This was interesting, however, he has already regained the ability to see color and his perception range is 100 meters (including through walls). Personally, I think if the MC had regained the ability to see color towards the middle or end of the first novel (chapter 50ish) it would have been better and more impactful that the MC was initially "blind."

he has a curse that impedes his senses, so how did he get his feelings out of control for a scent he can't smell? We only find out later that we don't know about his past just like the MC, he knows about himself BEFORE the transmigration (which has parts that are linked to his FUTURE, for example: his parents were burned to death by a mysterious fire that no one knows how it started and was difficult to put out, just like the Gop-hwa fire, but this was before the transmigration) but what about the past of the body he inhabits now? Nothing is clear at the moment. All the fainting he had was because of an ability called Gop-hwa that intensifies his emotions, which we only later discovered from the MC who was the influence that led him to all of this. So whenever we think "that's it" it turns out to be wrong in the future, and we discover everything as the MC learns on his own. Which brings us to: how did he achieve this? We only know that he has a burn on his arm that both before and now after the transmigration have, but the one now is a mark that remains from someone who has already been burned by Gop-hwa and the one before the transmigration? Somehow everything is connected and comes together little by little and even as readers we don't know anything that the MC doesn't know, ok maybe the system, but this has become too big to explain more unknowns.

because he is unprecedented special admission student who enrolls into the academy by the legendary famous principal with no test or qualifications, moreover he is just a newly awakened with no training whatsoever and his classmates awakened and trained since young

spatial perception allows him to know of everything that within his range which nearly kills him at the start until he properly learn how to use it and filter excessive and unnecessary information

Mana affinity like it's name literally gives high Proficiency in sensing, controlling and manipulating mana around him (no demerits noticed up till now)

Jack of all trades just like it's name gives him the ability to excel in everything until he becomes one of the better Average but doesn't make him specialized in any weapons or anything to be honest

the protagonist is quite literally babied all the time by being treated like they are a literal child. It sort of felt endearing at the start, but just kept on ramping up over time in increasing uncomfortable ways

one of the things sacrificed is the power of speech. The MC gets rewarded with massively OP magic that includes chantless magic in a world where it's rare. And not only is there a universal translator so that everyone can understand sign language, but there is telepathy. And still, the MC is obsessed with getting a 'confession necklace' that bypasses the need for speech... and conveniently confesses his desires.
