Sadly, no. It's not tied up with the twins. :(
Thanks for responding though.
This was about two close friends and the uke had black hair. So, when his birthday was coming up, the two had a friend who was a girl with pink hair and wanted to confess to the uke.
So, the girl asked for the seme's help and they arranged this surprise and the girl confessed.
This is yaoi btw and this is the only scene that I can remember. ╥﹏╥
