>>52880522yumanea (that girl linked yesterday) is pretty cheerful and after 3 months of watching her the only "menhera" moment i've seen was her saying "gee i had a bad day at work, was really stressful glad i am home to play some games" and moving on.
jeanfaymas plays retro and is pretty cheerful too even when she brings up serious topics she stays positive
i wanted to add sleepy and ami but they had their moments when they rant etc especially on twitter so that would be a stretch
lumi is also pretty cheerful but she's streaming to stay that way so yeah
