It's really sad how things ended up for Vesper. He was genuinely a good guy who just wanted to be friends with the girls and have fun. Instead, he ended up getting bullied to graduation by the loud minority of unicorns who couldn't stand the idea of male and female holos interacting.
Vesper was the Stars who respected boundaries the. The hate he received from those who couldn't accept him just for existing was crazy at a time I remember sometimes 20 threads being made on the same day from unicorns to harass him. It's a shame that we lost such a funny and kind-hearted talent because of toxic fans.

Vesper deserved better, and it's a loss for everyone that he felt the need to leave.

What makes it even worse is how some of Kronii's fans went after him just because he had friendly interactions with her. Kronii has always been clear about wanting to collab with whoever she wants, but the backlash she and Vesper faced was ridiculous. He didn't deserve the hate, and neither did Kronii.
And honestly it was obvious since debut that Kronii was going to collab with Holostars.
