What was boyfriend life before he was adopt by sarv?
I'm glad you asked! I've been thinking about this for a while now.
Boyfriend was an orphan up until he was around 10 years old. He lived at an orphanage, but often times ran away/would sneek out to spend time with Pico and Piconjo (who are also adopted in this au by Tankman). Pico's family were really the only people who made Bf happy in those times.
Boyfriend was always scared that he'd be prevented from seeing his best friend if any of the caretakers at the orphanage found out, so they kept it a secret
He was bounced around to a few homes, but none of them up until Sarv stuck. In fact, when Sarvente first adopted him he thought she would return him as well, and it took him a while to accept and realize that she wasn't going to leave him behind.
Since all of that was pretty sad and angsty, here's some Bf and Pico as children playing games
