Miren ga Michitara

Satomi currently works as an apprentice gardener and is in a complicated relationship with a soon-to-be-married man. He used to be a teacher, but he thought of himself as a sorry excuse of a teacher back then and even until now. Though one student still lingers in his memories, memories which he's trying so hard to forget. As fate would have it, Satomi meets his student again: Usui, now grown up and a teacher. Will the two of them be able to settle things from eight years ago and find closure?
