I mean, Weikun wanted to bring Ihyun to Chicago and tell him then that his gender started to change, so Ihyun would've had nobody to turn to... so yeah, he leaves and starts painting in Paris (Yuni invites him)

Can someone who read the novel pls tell me what happens ? like important spoilers ? I want to read the novel but unsure
