Welp this is either good or very bad,
Good: Tadano will be take way more notice of Manbagi and start feeling different towards her to the point it’ll be mutual.
Very bad: Tadano will notice her feelings but notice that he doesn’t feel the same, and eventually notice he feels that way only towards Komi-san.
Or the random card: he becomes kinda awkward around her and is dense, so he ignores it cuz it wasn’t something he was meant to hear.
