Um no mate, that's not how this works, isolating one from all other friends but yourself for a few weeks will not magically make any girl fall for you especially not one who's already really close to another, and ESPECIALLY since she's shown NO signs of liking you like you do
Also
What? Haven't we gotten closer over the past few weeks? I thought you might be willing to accept me
He sounds like a whiny child WAAAAA WHY DOESN'T THE GIRL I LIKE LIKE ME BACK WHAAAAAA, I DID SOOOOO MUUUUCH, that's what you sound like sir bum
Ah yes, guys when the girl politely turns you down remember, you don't have to accept their rejection- is what inferior Hiro over here would say, bro she friendzoned you as nicely as she could, take the L and bounce, people who can't take Ls are beyond scum
Especially since your implying there's a "hard way" now now mate, we do NOT need to go down that route, do not make the perception of us men that much worse, you'll bloody bring down the whole gender with you
Rouxi... RUN,
FASTER
