Well, to be fair, this show isn't really a "slice of life" show. It's a romantic drama; it revolves around a central triggering event and has a developing plot that will result in a defined conclusion. That being said, it probably is the Japanese call "iyashikei" -- a "healing" anime, due to the calming, heartwarming tone of most of the episodes. Slice of life shows aren't the only ones that can be heartwarming.
