Do we know if Sumo went to college?
Until she read the letter she was just one of those teens who more concerned about her image( and a slight bully)
I am guessing after she read the letter, friend in her tried to push him away form her so atleast he will study further and make a career?
By then she already lost her parents.She wants her only true friend ( although she doesn't admit) to have good future unlike her.
We were also shown her to be a good cook even back then. She was cooking for Shravan.
Just my thoughts..
