His 'acquaintance' - A Hisoillu Wattpad

You'd never expect a mature, non-showing emotion assassin being with a immature Cl-Magician. Apparently it was for Illumi's business.

Right?

Illumi Zoldyck Amorou.
Age:24
Height: 185 CM (6'1)
Weight: 68 KG
Part of the Zoldyck Family. He is married to Hisoka for his business, chasing after him, trying to kill him to receive his reward: all of Hisoka's money. But something stops poor Illumi Zoldyck from doing it.
It was his affection. He was the only one who ever gave him that, and had eventually fallen in love, on accident.
In this, you'll see a few things that resemble their relationship, although to Illumi it is unconventional. Hisoka was the first person to be considered a friend or at least an ally to Illumi.
