Gu Qi immediately understood what the old man meant. It must be that he and Nangong had no closer contact. They wanted to create more opportunities for themselves

they have made a mistake, not to mention changing a light bulb. Even if they change a house, they still don't like what they don't like

since nangongli has come, Gu Qi has no choice but to let him change the light bulb, otherwise they will find an excuse to scold themselves

it's just a light bulb change. It won't be long
