Ahh, finally... Even though there's a lot that I still didn't understand, but at least it's a lot better than before...
So... Aki once kissed a friend just for fun. And turn out that the said friend confessed to Ali, but Aki didn't actually love the said friend romantically. So Aki felt bad about it.
Probably because of feeling bad from it, Aki decided to make an arrangement and hook up with random stranger from the internet. While waiting for the said random stranger, Sara call out to Aki. Aki thought that Sara is the said "random stanger", but actually Sara just happen to pass by and call out to Aki.
Did I understand it correctly?
