I Love You Depite You Leaving me [Sasuke needed] [Not a romance thread]

My character is Sasuke's cousin. Despite everything, he has found she always has and always will be there for him. This is a role play to describe their relationship. It starts in the beginning, them choosing teams. Sasuke explains his feelings with Tsubaki, the only person he is truly open with, or that is tolerable. I am letting you decide how much Sasuke likes her.
Here are some ideas I hope to encounter through the thread.
Sasuke and Tsubaki go on a mission together and instead of cleaning up after Naruto, Baki is cleaning up his messes.
Tsubaki teases him a lot and he gets mad. He says some hurtful things but finds at the end of the day he can still count on her to have his back.
At one point, she has to kill her son brother who wakes up from a coma and Sasuke helps comfort her. She is a person that revolves around family despite not having much of one. [Feel free to say no to any or add in more ideas]

Name: Tsubaki Uchiha or Uchiha Tsubaki
Age: about 13
Gender: Female
Sexuality: She leans towards girls but she is bisexual
Personality: Despite having gone through a lot, Tsubaki is still a very cheery person. Her coping mechanism is laughter which makes her laugh a lot. She likes to joke around and have fun with people. Making missions for fun is also something she tries to do with her team. As said before, Tsubaki is very family centered. She will stick up for any member of her family someone tries to out down, even Itachi. This is the only thing she gets short tempered about. Tsubaki is also quite flirty with girls, helping chase girls away from him.
Summarized back story: Tsubaki had two older sisters and one younger brother. Her parents argued a lot and her father took her and her brother out for a walk the night if the massacre. They spent hours walking about and playing around, the father wanting to be away from the mother. When they came back, everyone was already killed and It a chi had left. Tsubaki was the first one home, her brother would have been the second. She saw her mother and two sisters dead in the ground and panicked. She was very upset over the deaths, not noticing her brother had fallen on his way up a few steps. He was out into a coma. Her father killed himself multiple years a range later leaving Tsubaki all on her own.
Fears: Large amounts of blood.
Other: Her team is an OC team. If you need any other information let me know!
