Lu Ziling always felt that there was no time traveler more cheating than him.
It's just that he traveled back in time to his gay friend's cheating novel, but he actually turned out to be the protagonist's childhood sweetheart.
The protagonist's childhood sweetheart, whose identity sounds awesome, is actually a hard-working character who was destined to be cannon fodder from the beginning.
Upgrading to accept girls is simply an extravagant wish. It is impossible to even become the protagonist's right-hand man. Just surviving is already exhausting. Time travel master, you can't play like this!
