Cupid is Struck by Lightning Vol. 1

For the right price (lunch, in most cases) he'll find out whatever you want to know about your crush, using his top-notch conversational skills and easy-going nature. But Shingo meets his match in the handsome yet terrifying second-year Ao, a boy whose gloomy presence doesn't hurt his popularity one bit. For some reason, Shingo gets tongue-tied around Ao, but when he uncovers a secret about the older boy - one that has nothing to do with the mysterious scar on his face - he notices his feelings begin to change.
