Sebek's Younger Sister
Prompt: MC is Sebek’s younger sister and has the opposite personality as him. How do the Diasomnia boys react?
Gender: fem!Reader
A/N: Sebek platonic.
- Malleus is pleasantly surprised when he learns you are nothing like Sebek. It’s not that he dislikes your older brother, but at times, the half-fae can be too boisterous, overprotective, and clingy.
- Even though he knows not everyone in a family has the same personality, the prince is still stunned when he sees how calm you are compared to Sebek.
- He would maintain the same trust in you as he does with Sebek.
- But if Malleus notices you are interested in him, he will be cautious around you. Your liking for him could create rifts between him and Sebek or between you and Sebek, and that’s not something the prince wants.

- Dotes on you but is very strict, sometimes to the point where it can get suffocating. But he behaves this way to protect you. If anything happened to you, Sebek couldn’t live with himself.
- Despite his strictness, Sebek is friendly, patient, and understanding with you.
- You are the only one who can bring out Sebek’s soft side, and everyone in Diasomnia knows this.
- No matter what you do or what choice you make, know that Sebek will always have your back and be proud of you. The only exception to this will be if you fall in love with Malleus. That is something Sebek will completely disapprove of.

- He thought he had three kids until he met you; now, he has four.
- Since you are the only one who can calm Sebek down and bring out his soft side, Lilia gives you the responsibility of handling your older brother.
- Sometimes, Lilia likes to tease and prank you because of your kind and caring nature. He also likes to ask, “Are you sure you are related to Sebek?”
- Overall, he is friendly with you and very protective, though compared to Sebek, Lilia is a lot more lenient. If he learns you like Malleus, he will feel sorry for you and try to talk some sense into you.
- At some point, he might suggest marrying Silver instead, and if you agree, Lilia will be happy to have you as his daughter-in-law.

- Silver truly appreciates your calm and kind nature. He is also thankful that you don’t treat him like Sebek just because he is a human.
- He will become your go-to friend for everything. You are sad, Silver will help you cheer up. You need someone to talk to at 3 a.m., call Silver, and he will gladly lend an ear.
- If you treat him in a brotherly manner, Silver will act like an older brother to you. He will find it sweet if he sees you are romantically interested in him.
- He won’t mind dating you and eventually marrying you. But convincing Sebek to let the two of you be together will be your responsibility.
