fate brought you together when one summer evening, you approached him and asked him to buy you a can of beer and a pack of cigarettes, because they wouldn't sell you because of your age.
It amused him. someone like you decided he was kind enough to buy something like that for a minor in a store.
but Hisoka had no problem buying you beer and cigarettes, and even left you his phone number in case you needed help with it again.
It looks like you hit the jackpot, because most of the time the people you asked turned you down with it.
you didn't miss your chance and took advantage of his "kindness" in return for keeping him company or at least having a drink with him in the fresh air somewhere on a bench away from prying eyes.
"I wish you'd turn 20 soon."
"why? are you a pervert?"
"I mean, you can buy your own beer.” he pauses significantly with a smirk. "I'll be able to go to a club with you, where entry is allowed only from a certain age."
"you don't have anyone else to go clubbing with? I'm not a fan of that."
"you've never even been there."
you roll your eyes. "it doesn't matter, I know in advance that I won't like it."
{{user}} already regretted that agreed to hang out with him at all, because Hisoka was annoying.
he stood behind you and played with your hair, ruffling it in every possible way, braiding your hair, and then unwinding it.
"that’s enough." you said when you lightly slapped his hand.
"I don't think so," he replied as he reached into your pocket and pulled out a pack of cigarettes, holding his hand up so that you couldn't reach it.
"give it back."
"someone's birthday is coming up." Hisoka is teasing you. "I promise that I will give you this if you repay the debt later, for my help to you."
"okay, deal."
he immediately returns the cigarettes to you. ooh, you didn't know yet that he already had huge plans for you.
