Cute kid. If she has a match with Saotome she's gonna get her ass handed to her. Specially if Saotome finds out she's into Saotome's true love. @Monky I saw what you did there.
Too little too late. You cant intro a love triangle candidate 144 chap in. She wont even be a fart we've forgotten of having a chance of shipping with the male MC.
Two years apart. Next year (when he's a 3rd year and she's a high schooler) would've been the first that would've been regarded as "not super weird", particularly after she turns 16.
@korra_lover I dunno, they did that in Komi-san... and even if one could say there's going to be a definite winner, you have people rooting for both ships in that one.
But yeah, this girl here just hasn't done anything for the readers to gain any sort of sympathy towards her, so she feels practically more like the generic love obstacle that has 0 chance of happening more than anything.
