If you want something that's just sweet and is kind of silly, this might be okay for you. I know a couple of people who enjoyed it for that. I went into it curious due to the cat thing, but although I kind of enjoyed it for a while, I wound up disappointed. How much can you watch a guy swat at a cat toy?
The wigs. It may just be me, but I hate it when they use wigs in BL's. It never looks good. I think they even had a wig on a little kid in one scene.
The cat MC seemed way too innocent to be in any kind of a relationship. By the time the series ended, I was actually happy nothing happened between them, even though MC1 said he was in love with MC2. Because...ick factor. I couldn't even imagine them kissing.
The secondary romance. One guy had a brain injury that prevented him from showing emotion. This made it pretty much impossible for the romance to develop. I mean, we could never tell what the guy was thinking.
The girls didn't interest me at all, although the hamster thing was cute for about a minute. Add in the beach scene near the end, which was forced as hell, and the whole thing pretty much bombed for me. BUT! If you want cute and sweet, don't care that they MC's never get physical even for a kiss, and have some time to kill, go ahead and try it.
