Gokuraku Smile

Kurisu Riku is a 16-year-old with a somewhat small build. She's a huge fan of "Enahara Haruka," an actor whose selling point is his coolness. However, by chance,Haruka (real name: Echizen Yasujirou) transferred to her class, and she found out that he has a horrible personality, and it totally destroyed her image of him!!However, even though she's perplexed because of the difference between his image and his real personality, Riku is slowly drawn to him?!
