Slowly Passing Clouds Contain Sunshine and Rain

You Yu traveled through time, and following her was a useless system 2752. You Yu's identity in time travel is cannon fodder, sidekick, passerby, scapegoat... Except for the protagonist, any identity may be! It couldn't be more humble! You Yu's role is to "help the protagonist resist harm, give him golden fingers, and even be an emotional nanny..." I couldn't be more heartbroken! The first time You Yu opens his eyes every day, he asks three times a day: "Can I lie down today? Can I be a salted fish today? Can I face the sea today and see the spring flowers blooming?" 2752 Will then gloat and reply: "No! You still have to get up and finish your day as a social animal." It couldn't be more miserable.
