The Secret Recipe

Horikawa, newly appointed president of her school’s cooking club, is rather thrown when the club’s newest recruit, Wakatsuki, comes to her with a request: a kiss. Wakatsuki suspects she might be gay and wishes to test the theory, and since she joined the cooking club only to attract a good husband, she plans to quit the club if her theory is proved correct. Desperate to keep the club numbers up, Horikawa agrees to the odd request, and much wacky Les Yay ensues.
