My memory is kinda hazy so maybe some different titles will get mixed up here. So the MC got yin and yang eyes, she can sees ghost, exorcise them. Mc at the same time also went through business route where she and her grandma and sister (?) sells the bun in market, eventually they build an inn mansion with hot spring within up on the hill. I dont really remember the ML since the romance is so little, but I remember their son will inherit the mc's eyes and can see the ghost. Please help me
