That crush he was talking about is Ari's sister

calm your heart down, darling. that crush is actually Ari herself

But I won't lie tho, his indecisiveness on whether to let go his childhood first love is blaring red flag to me. He even openly admitted on being equally committed on Ari and his first love which screams cheater vibe tbh

But her hair is blonde tho.
Anyway for real... I mean it possible to hold some precious feelings for his first love but it shouldn't be the same with what he have for Ari at the moment

The things is, it's not JUST his childhood first love. It's the first person who was truly on his side with no ulterior notice or goal, she saved his life more than once and was something that somewhat tethered him to reality while he was on the battlefield.

I think it's more of a gross cop out to say that "oh, it was just ari all along!" Instead of actually healthily addressing his feelings. Additionally the story takes the time to shit on polyamory by saying, word for word, "they are all garbage, two-timers, human scum, and scoundrels." When talking about whether you can love more than one person at once.
