not logic, but if we put parameters or something.... gaming and RL is different after all...
Edit: checking my prev reply, I didn't use 'logic', I said terminology or concept... you get what I mean...
but is that all you got to say? what about the first part about your theory being applicable to both ship?
the difference is, Tsubame likes him and may be on the border to love but not quite there yet, but Ishi don't even know Iino likes him (and most probably won't believe it either if she confesses, going by his personality so far and their history together), and you expect he to suddenly see her in a different light just like that and accept her? less probable that Tsubame falling in love with him
less probable doesn't mean impossible, but your previous statement applies more IF Ishi felt compelled to accept Iino's feeling suddenly IMO...
