its just the virtue signaling that people find obnoxious. It's pretty clearly the videos purpose is targeted at females to make his little catboy self insert seem like mr.niceguy who's fictional waifus are actually super empowering and not a coomer like everyone else!!! (aka cope)

the video itself and it's ''messege"(if it even has one) isn't bad, it's just the perfect storm of self-insert, reddit, and virtue signaling to make it almost universally annoying.
the aesthetic of trying too hard to be cute is annoying and can come off as predatory in the modern discord-groomer age (picrel).

Oh and he's also an obnoxious millennial.
