What I'm hoping is that this is where the whole house of dysfunctional cards comes down: They go find Ma-chan, she tells them what's up with horrible mom, A-chan doesn't hand over the money (he said he would over the phone but it's not clear that he actually has yet, and saying over the phone a contract is not), they toss her out on her ear and live together again, and he's finally forced to confront his feelings for MC.
