Kimi e Musubu Happy End

Miyano is a corporate drone whose both mind and body are now exhausted from being overworked by his black company. One day, Q, a beautiful and mysterious young man who claimed to be the Cupid, suddenly appeared in front of him. Apparently, Q has been observing and taking note of how hard Miyano has been working without even so much as a complaint. After explaining that he can make Miyano's love come true, he asks Miyano who is the person he'd like to have fall in love with him. To that, Miyano says, "I want to be in love with you." However, Q's true motive is to make sure that his future parents' love comes to fruition!
