She refuses to lean on him, prioritizing her resolve as an athlete over her personal feelings. Meanwhile, Hina’s presence adds further complexity, blurring the lines between friendship and romance. From midnight conversations in the kitchen to fleeting morning interactions, their shared life is becoming inextricably linked. It is no longer just about the sport or the crush; it is a raw exploration of how two people influence each other's growth, proving that every heartbeat counts when you are chasing the same dream.
