▸ it was all you, only you

▸ kou was used to using his good looks to his advantage

▸ he decided to use it to charm you

▸ unfortunately, you were too pure in the corrupted world

▸ firstly, he was inspired by you

▸ how you seemed to make words flow out of your mouth into a beautiful melody

▸ later on, he decided to debut

▸ idol and fan interactions were scarce and fans weren't the idol's first choice for a relationship now were they?

▸ he treated them as though they were a precious treasure

▸ when yuma accidentally dropped one of your albums, kou was ready to fist him right there and then

▸ he only calmed down after ruki talked to him

▸ later on, he went into his room and opened a picture album

▸ it had all your photocards, every single one placed carefully

▸ a smile on his face as he caressed your face on the cardboard piece

▸ soon, you and he could collab together

▸ oh, how happy he was!

▸ you denied it naturally 

▸ but kou

▸ kou happily went towards you

▸ but you refused him 

▸ this made him drop the smile on his face

▸ "why??"

▸ couldn't you see how much he loved you? how far he would go for you?

▸ "i'm..." you hesitated, making his eyes darken in discontentment

▸ how could you keep things from him?! 

▸ kou was supposed to know everything about you

▸ "already in a relationship" you answered with a happy smile on your face

▸ something snapped in him but he kept a smile on his face

▸ "how unlucky me" he said as if he was unaffected

▸ with his manipulative ways, he found out the name of the person dating you

▸ "they certainly are lucky to date you!" he congratulated you

▸ and he behaved naturally around you

▸ as if he didn't confess to you, as if he wasn't rejected

▸ you were thankful to him but you didn't know his true self

▸ a couple of weeks later, kou visited the person dating you

▸ and killed them

▸ "who... why-" your so-called lover groaned as he got punched

▸ "[your name]'s true love!" kou laughed in glee

▸ and he forced the person to drink some alcohol and pushed him off the balcony

▸ "opps!" he smirked as he pushed his hair away revealing his hidden red eye

▸ erasing all evidence, he went back to the mukami mansion with a happy smile

▸ "you seem rather happy," ruki said to him

▸ "well yes," he smiled and went inside

▸ now all that was left was to make you his
