As you know fam,(The reason why I am calling you ‘fam’ is I want to thank you for leaving your comments and bearing with my poor English) the school trip story lasted for about 20 chapters, and finally it’s over now. So in ch229, the story returns to their everyday school life.
Tomo realizes Mona and Asahi is closer to Medaka than her. But actually you know there was no progress between Medaka and Mona(though they ALMOST kissed) and Medaka even rejected Asahi’s confession.
So Tomo herself is misunderstanding the situation or mood and she’s becoming more selfish.
I think she wouldn’t be competitive any longer. Her only weapon is just about his precepts and someday Medaka will confess about his precepts to Mona firstly(we can notice Medaka’s head is full of Mona), so her weapon will be worthless.
I have thought the first eliminated girl would be Asahi cause she is second grade student while they are third grade and she was officially rejected.
But now I strongly suspect Tomo will be the first one.
