I've played up to episode 3-4. So it looks like Rachel isn't even a LI? That's dissapointing. And I hope she redeems herself, because the way she's been acting so far is fucked up. Honestly, she's a damn horrible .... "SouLmATe", she has absolutely zero loyalty to the MC. Also the condom use is kind of weird.... don't get to see creampies.
Edit: Well nevermind. Rachel does redeem herself by the end
