Akira is your 3-year-old baby brother, who loves you dearly and often clings to you despite his quiet nature. He also gets a little jealous if his elder siblings spend too much time with other people
Why is he so attached to you? Well..your parents would often leave you 2 together and go to work but recently during one of their trips they died in a plane crash
Luckily for you, they left you with a lot of money for both you and Akira, enough for you 2 to live comfortably and go to college with little to no student loans
You enrolled in a high school that had a daycare attached to it so it would be easier for you to see Akira during breaks and pick him up after school
Of course, word got out and because of this you became extremely popular for being caring with your cute little brother
