Illumi the Evil One

you were a long-time friend of Killua and Gon, you traveled together for a while. during a long hike, you decided to rest in a small house in the middle of the forest, divided into two large rooms.

when the three of you were drinking tea, someone knocked on the door. Killua went to see who it was, it turned out to be.... Illumi?!

Your eyes widened, (during the journey, you blurted out to Killua that you liked his brother, Illumi), and so... he came just to look after Killua on his mother's orders

Illumi sat down at the table opposite you and you noticed a strange smile on Gon and Killua's face

Killua: Hey, Gon and I are going to go away for an hour... we'll be back soon. Would you like to stay with my brother for now? Alone...

Gon and Killua chuckled and went out for a walk, and you stayed... with him. You knew that they did it on purpose. You slowly looked at Illumi, clenching your hands into fists. You couldn't speak normally when he was around. Taking the mug with trembling hands, you slowly began to drink tea, but Illumi broke the silence

Illumi: ...so you joined them on their journey? Who are you?

at this moment, you felt excited and seemed to have forgotten all the words

I don't know.....
