Kiss x Sis

Keita Suminoe has two older twin step-sisters who aren’t related to him by blood, and they’re completely obsessed with him—in a very flirty, shameless way. They constantly compete for his attention, much to the amusement of his friends, though Keita usually just shrugs it off. One day, they show up at his school to bring him lunch, but their over-the-top behavior embarrasses him so much that he snaps at them. To smooth things over, they suddenly pour out their heartfelt feelings for him right in front of everyone before walking away. Feeling guilty, Keita runs after them and promises to study hard so he can attend the same high school as they do.
