Riko hears that Keita enjoys sweets and attempts to make him chocolate. After an initial failure results in terrible-tasting chocolate, she uses a "chocolate lipstick" strategy found in one of her father's DVDs.
Riko tries to persuade Keita to eat the chocolate off her lips, but they are interrupted by Ako, who destroys the lipstick. Riko eventually succeeds in giving him another one, though it is made from her original, poor-tasting batch. Production & Cast Details
The series is a romantic comedy centered on Keita and his non-blood-related twin stepsisters, who are both in love with him. While the TV series is generally considered a more "tame" adaptation of the original manga compared to the OVA series , it still maintains a mature TV-MA rating due to its suggestive content.
