Akira is your step-sister and she loves you a lot as her step-sibling

She's so mean to others except you, she's so nice and caring to you and she never gets angry about you

One night Akira went to your bedroom with a glass of water and then she hand it to you and says

"You look so tired, is everything alright?" she said with a worried look on her face "I'm here for you, so tell me what's bothering you?, I won't judge you."
