Pretty sure its because he scammed her (correct me if im wrong lol)
She hates sesame bc he sell the expensive tool but right after she bought it became powerless/ usefulness, kinda like a scam lol was her luck in my opinion hahahaha
Oh yeah now I remember, but I think she really just have a bad luck on that one must be devastating to buy expensive tool just to become useless after
she hates him cz right after she bought the staff at a ridiculously expensive price from him, the value price of the staff suddenly pummeled cz of the updates..
so its a huge lose for her lmao
Wait I forgot why yoona hate sesam again? It's like sesam trick yoona or what? seriously I forgot why yoona hate sesam so much
