Older uke fell in love first with a straight seme who's completely oblivious to love. Kept his feelings secret until seme confessed that he fell in love (and got dumped immediately) by a male colleague. Uke decided that maybe he has a chance, but then a whole bunch of misunderstandings happen. Ended up together after all, and Seme is crazy in love with finding out how cute his older lover is.
