Do you know this yaoi manga?

It's about a boy who's in love with his friend but never confesses. His clmate notices this and teases him lightly, however, he also offers to be a substitute for him. At first he rejects, but eventually he gives in and they fall in love (the seme was in love with the uke the whole time and was teasing him fondly I guess). I know for sure it's not Calorie or Ano Hi Bokura Wa Koutei De. I really want to find this manga because it's the first yaoi I read, so help is much appreciated.
