Okay, it was cute, but I had a couple of problems with it.
First, no one explained to Sora *why* it was a bad thing to say they were together. I totally get not wanting to have sex with the 'rents around, but (and maybe this was the tsundere part of him?) it felt like he pushed Sora away a little too much. And the ending was good that Sora came back, but it still felt like the other guy didn't really accept it completely.
For the second one, as someone pointed out in the comments, the blonde guy never actually said anything about loving the salaryman. He just kept saying the other guy would fall in love with him, but nothing about him loving the first guy.
