Hmm... kinda similar to "You're the best" but not that much. The chord progression is similar, and maybe the vocal composition.
To be fair, YG loves Mamamoo, that's obvious since many years now, but I don't really mind, especially because it's Babymon, at least they could pull off a Mamamoo type of song.
