Omi Sensei no Binetsu

Tsukasa Omi has never been able to let go of his first love, a close childhood friend he affectionately calls Su-chan. Now stepping into a new chapter of his life as a recently hired teacher, Omi finds himself returning to the very halls of his alma mater. It is within this familiar yet changed setting that he encounters a striking figure—a student named Sugimoto who bears an uncanny resemblance to the person who has held his heart for so long. Upon learning that Sugimoto is actually Su-chan’s nephew, Omi’s lingering feelings quickly transform into a focused fascination with the young man. Driven by nostalgia and a deep-seated emotional attachment to his past, the new teacher begins to take a persistent interest in his student's life. However, this unwanted attention does not go over well. Rather than feeling flattered, Sugimoto finds Omi’s constant focus irritating, setting the stage for a tense dynamic between the nostalgic educator and his thoroughly annoyed target.
