I totally understand; I fell for a character but I start bullying him when I was talking with my friends bc I was frustrated I couldn't get his rare CG. Taking out the frustration on fictional characters is good, but I easily fell back to fangirling after I got a limited CG from an event.
I can really relate to Wada's celebration picture. I don't spend money on gacha games, but when I got a girl I had been wanting since even before she was released in Kirara Fantasia last fall, I was just like Wada in that picture. It made me so insanely happy.
Of course now I can't get another one I've been wanting since before her release (requesting her to be added for over a year) and it really sucks.
