Yonoi Tsukihiko's Happy Hell Vol. 4

ORANGE YOU GLAD WE MET?And so the impossible happened: Yonoi Tsukihiko, who doesn’t believe in love, has fallen in love! His heart now belongs to Hanabata Mikan, but relationships are something new to the cold and calculating company president, so he reluctantly lets the orange farm heiress take the lead. Despite that, Tsukihiko struggles to keep Mikan happy, especially now that she's demanding a surprise from him for her upcoming birthday. Worse, his cousin and rival, Seiya has also set his sights on Mikan, and he's a much smoother operator than Tsukihiko. Is he in danger of losing Mikan? Should Tsukihiko give up or will he rise to the challenge posed by both Seiya and Mikan?
