I love that Seki is the ultimate boy able to wingman a ship without even being present. The Side ship is better than main indeed, but the main guy is downright the best character, we need to find this boy a good female lead
I am not convinced the Ship has sailed, since so far the only one able to actual play keep up with this crazy girl at all both IC and meta wise is Seki, so Pon needs to get his game up.
Edit: Iama do a joke end ship prediction right now
Its going to be Mari x Pon and Seki x Kon
