How BTS became that person they are on the War Of Hormones MV? Here's their story.

Warning: Long post

JHope: Jhope has the most perfect life in the group, his family is open about it, his family knows he has this group of friends who's all raggid and wild and dark. But it's okay, maybe it's from his parent he got this positive genes. JHope is the energy pill of the group and also the warmest kid on the block, whenever they gathered up, they always went to JHope's home to hang. Whenever they're at their house garage Hobi's mom would come in an brought them juice and pastries. Maybe that's why he's the energy pill.

Jimin: the momma's boy. He is the most soft-hearted member like you could say at first look, you could tell his mom's the one who's making him dress those jumpers, polo and bright pants. Whenever he hanged up with the group, he was teases by BTS as too formal and too polished, until they started to raffled his cowlicked hairstyle into a wild and free hair, unbuttoned the first 3 buttons. But Jimin likes the jumper straps that his mom made him to wear.

Jungkook: the 2nd to the last to join and the orphan. He was living in a really religious orphanage, but as he grew he gets sick by how everything goes, too modest, too quiet, too holy. But Jungkook's heart, as he grew up as a teenager, turned to be wild, troublemaker and the one who hasnt been chosen a couple of times by some parents who wanna adopt because of his mischievousness. Until such time, he chose to run from the orphanage and lived in the streets for long. Til this most influential family passed him while he's struggling inside a large empty box where he is living, the family stopped and this kind boy who's not so far from his age , handed him a box of his old dress and gave him a food before they drove away.

Jin: the last to join the group, from a perfect and most influential family on their town, everything is so perfect around him but he's missing one thing. Friends. This is when, a group of guys came to cross their mansion as he was sitting alone in their built-in park. He got curious and followed them as he saw that kid he helped from the street before. He was just hiding as they followed him but Jungkook remember and noticed him.. He hanged out with them and there he found happiness with them and choose to run away from home and went with them.

Taehyung: was thrown away as a baby in a dumpster, but in luck a family saw him and adopted him.. Seems that the family who adopted him were kinda naturally bad-asses, but they're not criminals, just bad-asses. He likes lollipop as this was what his foster dad gives him whenever he cries when his (foster) big brother bullied him. Until such time, as him and his brother grew up, they became bestfriends and together they became partners in crime.

Suga: the bully, from a naturall badassed family, and the only child, suga grow up to be stubborn and spoiled. Lazy. And always became superior to his wills against his mom and dad, until such time, his parents brought something home that he never liked. A Baby. He never knew he's going to have an adopted brother  and instead as time goes by, he bullied him and makes his little brother's life a living hell as he lives. Until such time Suga was involved in a mahor trouble but Taehyung helped him and saved his life, and when they grew up, plot twisted, they become the partners of crime, literally, as the bullies in their school. 

Rapmon: starts as a school nerd to sexy brain. Rapmon has no friends and was bullied as ugly guy braces who also had worst acne problem, a very bad hair style and very big googly eyeglasses. Turns out he became so done with all the bullying and choose to stand up for it. He remove all the steel in his mouth, starting to work out, fix his acne'ed face, change his hair style and does an overall makeover, everyone was shock by his transformation and was more amazed when he face these bullies, turns out the bullies learned their lessons and unexpectedly, the bullies bowed down to him and made him as their leader of the group(BTS).

Sorry for the long post. Here's for you.
