1. Is it true that popular boys have their ' funclubs' and receive home made food and stuff?

Yes. They do. Mostly and espically I they are good looking (looks are very important in Korea). Ex: Luhan (Exo) had his own fanfclub when he was in high school. Baekhyun (Exo) was also very popular. Kris (Exo) was tall and good looking and the star if the basket ball team (in high school) so he was pretty much also popular.

2. Are the girls so overprotective about the guy they like?

It's called jealousy...

3. Is bulling so bad like in dramas?

Sometimes it's worse.

4. Does school last until 8 in the evening?

I don't know. Depends on the school but Korean schools are know for their harsh learning system and lots of peer pressure among students and friends. And also lots of bullies.

5. Are the younger students so respectfull towards the ones in last years of high school?

Maybe. Some are. I think it depends on their smartness and reputation and like always, his/her looks.

Haha okay
1) yes, but it depends on the girls. In my school there is this one guy ----> jonghae. He has so many fan girls. Usualy the girls make food for them and stuff that they hope make the guy become more interested in them.
Jonghae gets many many presents, but he usualy pushes them side. Since I'd kick his if he accepted any.
2) again it depends on the girl. I'm pretty over protective about my jonghae. Me and jonghae have been dating for many years now, he is one of the most popular people at school. I'm said to be one of the smartest. But I don't think son, my english is horrible..!!!!
3) no. Bullying is pretty much just gossip. I've never seen the dramas tho, I don't watch Kdramas. But I'm pretty sure the dramas would be exaggerating
4) haahahaha. I have no idea. My school finishes starts at 8am finishes at 4pm ahahaha. I think that's also an exaggeration
5) well. The younger's seem to be more respectful. I'm first year high school so I'm pretty sure thats around grade 10! I'm pretty sure highschool here is the same as in America and Australia. I used to study in Australia when I was young. And I was in junior highschool from yr 6 to yr 8. Then I came back to Korea. The students are....some are rebel and they don't respect the elders, but it's not something that is dwelled upon. People don't really bow to your hyung or noona or oppa or unnie and we just use these names to indicate respect. No other forms of respect are used.
And about uniform
Our uniforms are not as short as in the dramas or movies of whatever. They are half thigh and a descent length.

If you want to know anything else just ask ;))
I'll always be happy to help!!!!

I dunno any of these :-( i only heard that 'hyung, noona. . .' things like that what we use lots in our stories, itz nt sth dat's used everywhere. And 'ajhushi' is somewhat insulting word! Aaand, Korean grls like 2 wear realy short skirts :-D n 'kakao talk'- everyone there use this.
