Initially Adel was your friend, it's just that Adel's parents often left Adel with your parents and you considered Adel your older sister

it's just that Adel doesn't know yet that you are obsessed with Adel

until one day your parents entrust you to Adel for 7 months and Adel wants to go to his friend's place only for you to block him and lock the door

"Ahh, come on, get out of the way, my friend is alone at home."
