The super popular CG collection from the original Himawari no Tane has finally been made into a live-action film! Tanaka is a corporate slave who always stays up all night and comes home in the morning. Exhausted, he sits down at a cafe feeling depressed about his current situation, unable to change jobs or get a girlfriend. Then Kaori, a married woman from the same neighborhood, appears. Moved by her kind smile, Tanaka consults her about his troubles, and she invites him to her house, saying, "Let's continue our discussion at home." As he goes to Kaori's house to continue his consultation, she suddenly embraces Tanaka, and Tanaka, led by Kaori, becomes immersed in an extramarital affair.
