So far i'm really enjoying this. It's relaxing, so far all the drama moments are very believable and get resolved in a very realistic way, and so i feel i can just sit back, relax, and enjoy their daily lives without worrying about some of the more over the top drama that comes with a lot of other stories. Honestly, Sei acts very much like how someone his age would act in these situations, so i don't see a problem with a bit of jealousy. It means he really does care and love her, but he's also understanding and they cleared it up nicely, so now hopefully he can relax more about it.
