I need help

I need help. So I read this manga sometimes ago, but I don't remember the title.
All I remember is that, uke and seme are coworkers and they're dating. But uke is lonely because seme is too busy, and he feels insecure. He thinks seme doesn't love him as much as before. Apparently, seme confessed to uke when they were in high school?
One day seme gone on a business trip and uke was working overtime. And uke was with a colleague. The colleague reminds uke of seme before. Uke found him cute like seme of past, so he decided to tease the colleague. But then seme came and saw them(they didn't do the deed, uke was only teasing colleague). Seme got a little mad and decided to ram uke in the office. Somehow they made up afterwards lol
