>>35833661A cute nerd gf is nice on paper, but they're insanely high maintenance ("whoops sorry anon I'm too depressed to do anything with you but please run all these errands for me because you love me :3c"), they lack any manners ("Sorry I humiliated you in public anon. You know I was bullied for years so I just thought that's what you do :3c"), and the relationship will turn them into egomaniacs ("Yeah anon I know we've been together for two years but I think I can do better so I'm leaving you. Also I told all your friends you were abusive to me so they hate you now sorry :3c").
Tamashi looks like the exact kind of bastard of a woman who would pull all three of those things then cry that she's being harassed by trolls and exes when she finally gets exposed.
The only way to stop a cute nerd gf from ruining your life is to either A: Put them down just enough that they know their place, or B: Don't date one at all. And if you have a single functioning cell in your brain you'll go with option B either way.
