[To Yoosung, they would probably be friends. He knows Katsuki doesn't seem to use that word as easily as he does, though, and that's fine. Everyone's different that way.
He giggles at Katsuki's description of Alberto, thinking it sounds fond like how Katsuki talks about Rika sometimes.
It's... Not completely obvious to Yoosung that these are nicknames because for one, he's super gullible, and for two, some people on the Libra app just have weird names? But he does know about Katsuki's penchant for giving people nicknames, and he did mention "Nickels" carrying around coins. He just asks, because if he's wrong he doesn't really mind if Katsuki makes fun of him. It's not a big deal.]
