The Distance Between Us, The Space in Our Hearts

Shiori Mizunatsuki, a 32-year-old single mother, works part-time as an office clerk by day and raises her 9-year-old son Rikuto by night. She always tries to smile for her son's sake, but internally struggles with loneliness and exhaustion. Afraid to rely on anyone, she believes she must carry everything alone. When the new school year begins, Rikuto's homeroom teacher becomes Tsubasa Sakuma, a taciturn man with an aloof demeanor that makes him seem unapproachable to both students and parents.
