From Seven Seas:

Misono is an office drone with his own ups and downs at work, but thankfully, he has an ally: his senpai Shizuka, who happens to be a witch. Shizuka is always ready to lend a hand to those in need, but Misono thinks she should take better care of herself, since zipping around on a broomstick to run errands can be quite stressful. Is Misono’s over-solicitous concern for Shizuka driven by mere respect for this flustered witch, or could it be more? Let this magical romantic comedy cast its spell on you!
