It's Crack time! :NOT MINE and credits to the owner of memes and jokes:

Fang just moved into the neighborhood recently with his older brother. The nearby, school offered to have Fang into T.A.P.O.P.S high as a transfer student. Fang then meets the Boboiboy Siblings one by one and slowly, they start feeling more... whole and... well... things happened... The boboiboy Splits have a secret and they don't want anyone to find out. What happens if Fang finds out? What will they do? Will they sacrifice the one their love ones or will they sacrifice themselves? Or maybe, There's an alternative solution? Either way, we'll find out soon!! 《THIS IS INSPIRED BY @izacchii ON INSTAGRAM》 ●|| THIS WAS MOSTLY A SELF INDULGENCE FIC SINCE I CAN'T GET THE THING OUT OF MY HEAD ||● •●•\\MAJORITY OF THE THINGS HERE OUTSIDE OF PLOT AND STORY ARE NOT MINE!!

So yeah, Cahaya always found it hard to fit in with his siblings. Declaring that his only true friends are books and mathematical equations, which made it hard finding friends since... well... he was in a whole other level with them in terms of intelligence.
