Spoilers for Turning's webnovel
It's not isekai, but the MC of Turning, Yuder, more or less confesses everything to the ML, Kishiar, in Turning lol he waited a bit, but he was rather straightforward about it when he actually did it.
Eugene: No, I'm no angel or messenger of god. I'm just a random dude who got hit by a truck and woke up in this body. So yeah I got Isekai.
Alexis: I- what? wait what's a truck...?
