by the way thanks for your response and I am amazed you have read till 125 chapter of this manhwa 
you should try lookism or how to fight and I only recommend this two manhwa every other are copy past or plain boring (manhwa)

2 ok the thing is echiro oda always gives hint of something that will happen on later chapter so it makes people think he have thought the full story beforehand even Naruto does this but this author just thinks about the next chapters on the go

1 yes you are somewhat right and somewhat wrong 
in first class of the chainsaw professor he literally knew the move of one of the strongest(maybe) character and avoided it the second he attacked. and dude you have to agree this is just bad writing

I have made a response for you and no I have no understand of this manhwa other then what I have read and interpreted so take it with not super serious

3 it turns out that a character that has the ability to shape shift is a pet shop member and has been altering and allowing the place to infiltrated and even people in universe are commenting on how the place keeps on getting infiltrated

4/5/6 you are completely right there they don't ever really talk about other students of teachers even if they refinance them and it's just lazy

2 that is a valid claim but only now is it being revealed that nest is turning from a home that works to cure and heal people to more of a experimentation lab that is working to weaponize or profit from the people living in it but also could be wrong with later chapters so take with a grain of salt

okay spoiler warning so if you don't want to know then don't read I have read UpTo 125 this is to answer shinigami018

1 how the ability works is by memorizing the movement of opponents and predicting how they will moveit works best in fights that take much longer and with later chapters it becomes 2min fights not allowing him time to follow and track them

6 why would you send students on mission isn't it job of professional and where are the graduated people

5 in ch 3 there was many flag so how is there only 3 professor why where the fuck are other students

4 the biggest college in world consist of 3 professor and 30 students

there is so many problem in this manhwa like 
1 why mc always forget that he can read opponent movement
2 how the hell is nest the most advanced place in the world like how are they funded 
3 why is security so bad at there job

let's make one thing clear that I have stoped reading after ch 69 when they said the professor was just in coma and ofcourse he will wake up later with a hole in heart (literally)

nope only bullishit here this manhwa have good plot but no world building .this manhwa is worse in every aspect and it was my last hope in manhwa and now I think Korean don't know how to write good story . this manhwa have many plotholes which sometimes they fix after 10 chapters like when they explained why some human look more like insect than other which should have been addressed in ch 2 or 3

Good👌
