Summoning the Shark Princess[comprehensive]

I, the shark, have a relationship with a five-meter tough guy, and I am currently planning to cheat on him. But, how can you cheat on someone who has never even been in love? Admitting that I picked up a man has already made me collapse. How did you do it with your five meters? Maybe instead of cheating, I should cure my sleepwalking. I'm so worried that I'm bald.
