looking for a manhwa

i js rmbr the plot its like,,everybody has powers but not all have super powers due to which students are assigned to different classes(class A and F only as far as i can recall) so mc has light coloured hair and has the ability to know anyone's birthday and just like him,his classmates all have random useless abilities,(one classmate has an ability related with phones.Then a teacher(white-haired?) comes in and baam their classes run more seriously,a class A student with superhumane strength who's also bigger and misunderstood by everyone joins them and the teacher is apparently not ordinary,he was the previous mentor of strong power holders who work for the gov or more like they wanted to elect someone else as the president for which they had an entire plan of disposing the current president but the teacher and class F ruin the plan by kidnapping the acting-president,somehow the opposing side corner the teacher but his students likeeee display a threat video demanding the release of their teacher in expense of the kidnapped president's safety,

more details: i had only read the earlier chaps so the badguys had a nice front for the public but in actuality they wanted to take ahold of the governing power,the teacher is against it all and he's strong af too,he's still afraid that someone else he teaches will turn to the wrong path and he has these instances when he tries to distance himself from his present class,there's also a training scene where he takes the class to a dimensional training ground and uses a device to train them as per their quirk,we also have a traitor girl(violet hair) who doesn't want to mingle with the class at all and she receives govn funding,she tries to act against the plan by relaying info to the opposing side but in the end gets dragged into the whole kidnapping incident,also the video that's displayed to the whole public,it's obvious that they are the academy students but the blame is pinned on class A students becuz class F are supposed to be too timid and weak to do anything,um the president doesn't have a serious persona,he's an old man as a damsel in distress and is treated like a frail shell idkk like he acts like a pink princess and is treated as one too
