Yaoi
A Salary man and A detective
[️SPOILER ALERT️] I read the sequel first, i already know a bit how the story was going.. but i think in this prequel, the uke seems to have feeling of love to the seme... but the sequel, he didn't feel that he is in love with the seme or not, until they broke up... but there is no scene in this prequel that showed the uke said "i love you" to the seme.. so i think maybe he just didn't realize it..
