Momo is typically a cockblocker
They both fuck it up every time
During their first date Momo invited Mikan
Mikan only realized like ten minutes into it "Maybe I shouldn't be here, this is something Shamiko invited you to alone" and Momo tries to tell her its fine. Although Mikan is Momo's autism wrangler, typically if Momo fucks up Mikan's the first one who realizes it and might tell her how she fucked up. Like that time Momo called Shamiko fat and then said that them dressing the same was "unproductive" and kept autistically insulting her without realizing it.
Momo almost went to a date in a leopard print shirt with a riot shield if not for Gusion talking her out of it.
