?????????

Hi looking for a yaoi manga that it's about different couples but they are going to the same school and they're like a group and like 5-6 person they all are handsome and smart plus they have a nickname or something like that. The couple I'm looking is that they are supposed to go dating and have fun time alone his boyfriend (seme) brings his younger siblings with him and his brother and uke didn't get along and actually bullied each other and they fall into water and seme slapped uke because he said something like "he should go to hell" about his brother and then uke shooked and run away not much after seme come for him, uke was so mad and wanted to break up but seme didn't and in the end they had an amazing sex and everything was okay.
