Gravitation (2000)

S1E5 Winding Road

After their rehearsal, Hiro and Shuichi stroll through the park and spot two older men bothering a young woman. They jump in to help her, throwing out some witty insults to drive the men away. Grateful, she shares that she’s searching for someone very special. Hiro offers to help her find a hotel, while Shuichi decides to head over to Yuki's place. However, he ends up chatting with Yuki’s brother, Tatsuha, and they bond over their mutual admiration for the Nittle Grasper lead vocalist. Tatsuha's teasing gets a bit too close for comfort just as Yuki walks in. Later, Shuichi discovers that Ayaka is Yuki's fiancée, complicating matters further as the Bad Luck concert approaches. During the performance, seeing Yuki and Ayaka in the crowd prompts Shuichi to shout, "Yuki is mine!" This outburst reveals his newfound confidence, leading Yuki to declare that he wants Shuichi as his lover.
