Well, I dont pick up unknown numbers too, bit the fact that they didn't exchanged numbers by this time is really lame for both of them.
And I dont like this new girl (why, why do you always develop relationships trough the rivals, instead normal human interactions, authors?! Hate this shit) - it seems like she is not interested in game/guild/new friends, more like "oh you are gamer? I play games too" kind of character, who's gonna pretend interested and play whatever you like just to impress you and get your attention - this kind of things is just hypocrisy, that lead to relationships build on lying, ending with shit like "oh i dont like it at all, I just told you so you would be interested in me" 🤬
