Nathaniel hadn't been in love with a girl for a long time.
That is, since Marinette Dupain-Cheng rejected him in the 7th grade.
Later he became friends with Marc, they were very close but in the end they became just friends, more like brothers because Marc wasn't interested in anyone romantically or physically.
It was hard to be a teenager in Nathaniel's case, especially since he probably wasn't lucky in love.
But he devoted himself to his drawings, it seemed to be his only true love.
After classes he always went to the art class where various talented students met.
Some of them sang or danced, others drew like Nathaniel. But he felt that he could be himself there.
He missed his friend Alix, who after receiving the Bunny Miraculous had to disappear to travel in time.
