Ch 1-3: title story. Too fast too furious. It is cute though.
Ch 4: unrelated one-shot. Ngl, this annoyed the shit out of me. Friends who became sex friends with absolutely zero communication. They're not even sex friends with an agreement. They just do it when the seme wants to, making the uke seem like a convenient cumdump. Luckily for him, the uke knows him long enough to understand his feelings and is just waiting for confirmation about their vague relationship. The boss was just there to spark an argument between the two and finally talk.
