I maybe read this like 1-2 years ago but it starts with like the bottom following a black cat into an alley way where he meet the top who drank a spiked drink and is now like on the ground with a fever horny af. I’m terrible at explaining im sorry but the main characteristic of the bottom that is the most memorable is that he listens to his sister’s words as if they’re the law and she told him to always help people. Because of that he helps the top get off and this happens for multiple occasions even tho he doesn’t like it. I think top’s name is Aiya or Aya. They end up together in the end. I tried looking for this manga already and i have a feeling it was removed from the site. Don’t see why tho bc its a pretty mild bl. Also it came out with the second volume sometime last year i think and the sister comes back trying to shoo the top away.
I like how the Tang clan was first introduced as a bunch of scary dudes and now they just look like a doting father and brother to Soso. Its cute
