Well I don’t know what he’s got in mind but I support him. We know he’s not packing a big cock, but I wouldn’t be surprised if he was a Michelangelo with his tongue or something.
More than anything I think it’s great that they are going to stick together for the inevitable confrontation with the bullies.
Even if you put aside their historical abuse of Ueno, Moka has a LOT of reasons to be angry with them. They cozied up to her as a “friend” just to mess with Ueno and use Moka against him. From Moka’s perspective, every time they hung out together the bullies were laughing at her, knowing that they’ve done things with Ueno, and pretending they were people she could trust.
