The "gay stuff" is actually fairly brief (like 4 or 5 pages). This is mostly story. And it's not a terrible story. My one complaint is that the author seems to have exaggerated part of Oikawa's personality a little too much. While I wouldn't say he's /completely/ out of character, it's still enough to be a bit disconcerting.
Oh my god. That was cute and ridiculous. I've read a lot of yaoi at this point, but I don't think I've ever seen a foot fight like that. Also, the bottom of page 17. That's commitment. Oikawa had some odd facial expressions at several points, I think, but that just added to the goofiness for me. A+, I say.
