Who doesn't have their little secrets that they can't tell anyone? Like fishing, for instance—Gu Tao would inevitably sneak out to fish one day a week. He's no workaholic and never sacrifices his own time for work. That whole day, unless there's an alarm level two or above, he wouldn't take care of anything else.
But that's all in the past now, no one cares how long he fishes anymore.
Thinking about it, this seems quite good—the time nears for Tingting's due date, it's probably around the Lantern Festival when the baby will be born. Gu Tao now has plenty of time each day to spend with her. When bored in the office, he would even go knit with Liuzi.
