mostly all non-romance (excluding a little bl)

It's about a girl reborn into a newborn child's body in a cyber setting. There is the classic material art's thingy and virtual machinery and whatnot. It's a little cringe because the main setting is school, and these fucking kids that look like their 7 are talking about techniques in material arts. Apparently, the novel is really good, but again, I don't have patience to read novels. It stopped updating on here, but there are a couple of sites out there which have translated versions free.

A girl reincarnates into another girls body, except it's crossdressing as a boy. She continues to do so to not raise any suspicion. She apparently has a bad reputation at school because she is dumb, and also for thirsting over guys, and people thought she was gay. The MC is a flirty comedic girl who is really good at games, and the presumable ML is the boss/CEO of some type of gaming company, and he's trying to find her in person because she only goes in her gamer name 'black spades Z'.
