“You have to work hard to stay in love with me. Because if you change your mind in the future… I will kill you.”

Casper was always bullied by his elder sister’s best friend, Merlin. Tuwang-tuwa si Merlin kapag nakikita siyang umiiyak. So most of Casper’s childhood consisted of her tormenting him. Nariyan iyong pinahabol siya sa aso at pinakain ng sandwich na hot sauce ang palaman. With his baby blue eyes daw, all red and puffy, he just looked so damn adorable, sabi pa ni Merlin.
But then, puberty hit Casper and everything changed. Nawala na ang Casper na basta-basta na lang napapaiyak. Napalitan na iyon ng isang haliparot na Casper na kung sino-sinong babae na lang ang ipinaparada sa harap ni Merlin. But every chance she got, Merlin made sure she’d make Casper squirm.
Pero isang pangyayari ang bigla na lang nagpabago sa lahat. Nag-iba ang pagtingin ni Casper kay Merlin. He no longer saw her as the sadistic best friend of his ate. He was starting to have romantic feelings for her. Pero alam niyang hindi matutugon ni Merlin ang kanyang damdamin. Because he was just some brat five years younger than Merlin.
