Get To Know You

a majority of people forget to brush their tongue when brushing their teeth. agree or disagree?

i wonder if this is normal. this seems like a first world problem because it is. i don't want to boast my privileges but this is my problem and would like any experiences or advice. my mom always bothers me when I'm playing my mobile game. for some context, my mom is divorced and is raising me and my sister on her own. shes always pressuring me on grades and my future career, which I am exceeding what she "expects". she expects me to have straight A's and of course I have to deliver. i want to relax and play games with my friends but that's the only time she annoys the hell out of me, and when I watch BTS, literally the two things I enjoy doing in my free time. i am just trying be happy doing what I like to do, I'm not trying to make a career playing games. she took me to one dance class but then felt it was too time consuming. i really enjoyed dance but cant even do it anymore. this feels like I'm suffocating doing any of those leisure activities. she always guilts me by saying I'm wasting my time playing that, but I'm not sure what I would be doing? i finished all my work and practice and I want to relax for a bit but then she comes in and interrupts the time I have to myself. i just want to play with my friends without being always aware of the fact she's there. what should I do? there's nothing to change her mind, I just want some time to myself.

So I need help finding this manga I can't remember if I added it to my already read list and I can't go through that as I have 300+ manga's on there ands its gonna take loooooong.
So i'll tell you what I remember.
It was a fantasy one, where's there's like magic and things. So I guess when he went to the school to get tested hey let him choose what like thing he wanted to major in and he chose one that wasn't really popular and he was the only student. One scene was he got back and his dad was excited to what he chose ad he told them he chose that department and they were like WHAT?? and as the story goes on he's actually really gifted and learns things quickly. He has a strict teacher who I think sponsor's him to go somewhere.
It's a full-colour manga, in think the original raw are in Chinese. He has gold eyes I think not sure.
