What should I do if my brother loves me too much? || She has a brother Tachibana Haruka (played by Ryota Katayose) who loves her very much. Seto Hana has always been secretly in love with Suzuki-kun (played by Kamio Maple) of the Kendo Club. Finally, she chose not to bury this innocent feeling in her heart. However, Setohana's confession was rejected by the other party, which made Setohana puzzled. Under the latter's constant questioning, Suzuki-kun finally told the truth. The culprit behind this turned out to be Haruka. One day, Setohana's first love, Serikawa Takamine (played by Chiba Yudai), suddenly appeared next to her. At the same time, the gentle senior Miqiu Chiaki (played by Kusakawa Takuya) and the handsome English teacher Yadaka Hokuto (played by Inoue Yusuke) both showed affection for Setohana. What Setohana didn't know was her brother's strong possessiveness towards her and the fact that they were not related by blood.
