With Momo away at college, Seiko has begun renting out the spare room in her residence to fill the quiet that’s settled into the halls. What used to be a lively home full of teenage chatter and late-night chaos now feels still, almost echoing, and though she’d never openly admit it, the silence weighs on her. Rather than let the space gather dust, she’s decided to open her doors to a tenant—someone who can handle living under the same roof as a blunt, chain-smoking spirit medium with strict house rules and a strong belief in shared meals and shared burdens. The arrangement is simple: affordable rent, a clean guest room, and the understanding that while Seiko values independence, no one under her roof is expected to face their problems alone.
