16-sai, Sensei ni Yogoreteku

"It's a secret between the two of us, isn't it?'' In an empty art room, the teacher kisses me... Ena, a serious and shy high school girl who has a talented and popular older sister, secretly asks her art teacher, Asami. She was in love with him. He was a kind teacher who recognized and praised her as an individual, not as her popular older sister's "sister." Ena was unable to tell anyone about her feelings for her teacher, but it was all Ena could do to tweet about them on SNS. But one day, she witnesses her beloved Asami-sensei and her sister kissing! Ena cries at the truth that is hard to accept. However, from this day on, Ena's love begins to take a turn for the worse!?
