[System Quick Transmigration, Episodic Stories + Two Male Leads + Female Alpha, Male Omega + Narcissism...]
Note: The System appears and interferes very little. The focus is on the couples in each story. Each story will be around 200,000 to 300,000 words, so you can read each one as a standalone without affecting your enjoyment.
First world: I was reborn as a mad, obsessive, and possessive man, and decided to let go. So why is he being so proactive? [Two male leads + Both reborn, one has amnesia]
Second world: One day, I woke up as a 190-centimeter-plus, rugged female Alpha, even though I was a delicate princess!
Third world: I transmigrated into the body of a male Zerg with a hooked tail and somehow ended up having a one-night stand with an Alpha!
It's great, but it's too slow. It's warm, but not to the point. Can kill time
I didn't expect it to be well written.
