Koi no Mae ni, Amaku Hajimete. Hikaeme Elite-kun ga Watashi ni Dake Hatsujou shite imasu (Official)

Rui Sasaki, age 25, is single and has never been with anybody. People often tell her how young for her age she looks, but even she wants a chance at romance.
Luckily for her, a night out with a childhood friend leads her to meet the calm and very handsome Ritsu. Though most of the night ends in a blur, when Rui wakes up with Ritsu in her bed, she can only draw one conclusion… she's finally done the deed!
Ritsu, meanwhile, confesses that he has a problem… she's the only woman he's ever been able to sleep with!
Will their one-night fling blossom into romance? And can two people, each with their own complicated feelings about love, find a happy ending together?
