Get the JB mug.
That guy is the one for you, he is funny and clearly very hot, he has lot of intelligence and can be trusted. Even if a Jb is your crush it will be hard to make him understand you like him more than a friend. A jb can pretend that he doesn't give a shit but in fact he does. So don't be desperate if you feel nothing is coming back. In fact all Jb are very emotive but try and protect themselves
I can't love you

I am afraid
Jb i love you
