She wanted to go to a Hoyoslop convention in NYC, but her parents didn't think it was safe, so she convinced Pomu to come along with her, even though Pomu didn't really want to go and wasn't interested in the convention that was Finana's entire reason for going.
They get to NYC and it turns out Pomu had maxed out her credit card on her Hoyoslop gacha addiction, so Pomu had to pay for everything for both of them. This completely ruined Pomu and Finana's relationship and they stopped collabing much/at all afterward and it almost certainly contributed to Pomu's mental issues.
Oh, and Uki got invited along and joined their off-collab in their hotel room, so that didn't help.
