Himitsu no Asa ni wa Kiss no Ame

The young actor Hatogaya finally gets the chance to play the lead in a TV drama. After toiling in obscurity, Hatogaya was determined to dedicate himself to the success of this drama, but when he read the original script, he found many kissing scenes.
Hatogaya, who has no experience in kissing, is worried, so he makes a request to his co-star Seo, an actor who seems to have a lot of experience.
