Tsukasa is the kind of girl who takes half a volume of manga just to work up the nerve to tell her husband she cares about him. Sure, it's cute in a tsundere way, but the ice-queen act carries a chilling risk. What if another girl comes along who's more open about her feelings? Panty flashingly open, even? And what if she's also Nasa's childhood friend, the most powerful trope in romantic comedy manga? Anyway, here's Himari. You and Nasa have met her before, but she's grown up a lot since then.
