Minami won't know which ringtone is whose. Suzaka can just say whatever the hell he wants. He is probably egging Minami on because Minami said he would send a bouquet to their wedding and got pissed.
I keep thinking Minami is Mami chan because the senior modeller said Suzaka has only Mami chan and he's not fickle. I think it's contrary to his personality since he always had girls on both sides during high school.

Is there no one who thinks Mami, the fiance is actually referring to Minami (notice the similarity)? The phone probably could've been his mom as well. He said she's the heir of a company and absent due to studying abroad; basically non-existent. If it's not the case, I don't see how the mangaka could make a turnaround and create a happy ending.
Of course, I hate types like Suzaka and want his retribution but we all know they are main couple and they'll end up together in the end.
So I'll try to think positively before the next chapter comes. Heck! I even want to read the raws. I rarely want to be spoiled.
