This is quite a sweet, somewhat screwball romance. I like it.
As a side-note, I removed the "smut" tag because it's not really deserved; there's a sex scene at the very very end but it's not especially gratuitous, and isn't exactly explicitly depicted (though it's quite explicit that sex does happen—just enough to the point where I'm not going to downgrade the threat-level from "yaoi" to "shounen-ai").
