Yall I couldn't take the suspense and went to look for spoilers. I only read the character spoilers not plot spoilers, so I don't too much in detail about these characters.
There are 3 princes:
1st prince - son of green hair and a duke, adopted into the imperial family
2nd prince(ML) - son of empress and her lover, pretending to be princess
3rd prince - son of green hair and emperor, legitimate heir, crown prince
