James laughs when she hears sister-in-law's words. Indeed he knows their story from his dad… "Hahaha, so you only used him…?" He asks while sending a funny-sad smile at Mario beside him.
Mel nods while laughing.
Mario was getting annoyed seeing these two people laughing at him. Instantly he wanted to tease his sister-in-law...
"Yeah... you're right!!" A mischievous smile appeared on his face before continuing, "You always trick your grandfather. You said to him, you wanted to come here to study with me, right? But, instead, you went to the third floor to where my brother was. Damn it, sister! If only from the start I realized you were using me, I probably would ask you something in return."
