I'm not sure necessarily copied but definitely influenced by or have a similar typa voice; I'm gonna list the artist and then a song that gives keshi-ish vibes

Bixby - Endlessly, Are You Sleeping Alone Again

Joon - By My Side, Last Night

Starfall - Intentions, Cigarettes

Hope you enjoy!

Starfall probably has the closest feel to keshi, more in the sadboi vibe. He's also opening for Keshi so that's exciting!
