Matcha Made in Heaven

Chako Hananoki thought she'd found happiness in a handsome fiancé, but when she realized a marriage to him would mean a total erasure of herself, she broke it off and moved back into her childhood home in the country... only to find a strange man and young woman living there? She finds a way to coexist with them, but when her stalker fiancé follows her home, she declares to him (and accidentally to the whole village as well) that this new man in her life is her husband?!
