Undercover [Yumikuri]

For half a year Ymir has been undercover in a high school. Levi gave her the mission to be undercover as a student until the rest of the titans are defeated. In other words, she's looking out for them and protecting them until they're safe.

One day Historia joins the mission and supports Ymir which she's really happy about. But they have to keep their relationship a secret because they have the information that there are thiefs somewhere in the school who are after the queen, aka Historia.

Things get a little more complicated when they slowly can't hide their feeling for each other in front of the others.

[Ymir and Historia are engaged and are raising their son together (I called him Mir) Historia is 19 and Ymir 21 but they pretend that they're 15 and 16]
