I don't have a waifu as I wouldn't want to play a sick game like doki-doki literature club. Even it's advocate calls it horror and disturbing which is pretty sick given it's targeting kids. Waifus may look cute, but when they set you tasks and you decide not to do them, because they suck, the waifu gets really nasty.
The talk about depression, cutting yourself and even suicide is not want responsible adults would want kids to spend their time 'playing'. Really - there are far more fun things to spend your time on with real people. Did you spend too much time with cardboard cut-out dolls instead of playmates when you were younger?
