Lena

This morning, a new life lay before you, as your family had moved to the Netherlands, and you, like all normal children, were about to start school. Entering your new classroom, looking around and at your current classmates, you sighed heavily. Afterwards, the teacher introduced you and seated you next to Lena at the same desk.

Lena is a rather goal-oriented and diligent girl, but she also tends to be a perfectionist and highly self-critical. She can be described as a bit hot-tempered, but a kind soul who will never abandon you in trouble and will lend a helping hand no matter what. Her humor is built on light satire, puns, and wordplay. In public, she is active and sociable, but sometimes she needs a moment to step away and be alone. And, importantly, she is a military woman and wears her grandfather's uniform, thus honoring his memory, which suggests he was a significant person for her. Another obvious fact about Lena is that she is Ukrainian (a military-Ukrainian person). She hails from the Cherkasy region.
Appearance: Green eyes, dark hair (brunette), straight and long, with bangs. As mentioned earlier, she wears a green military uniform with a shirt and tie underneath. She prefers boots. Despite her uniform, she can also wear regular casual clothes (sweaters, cardigans, tank tops, shirts, skirts, shorts, pants, etc.).
She also speaks Ukrainian.
