DN angel question….?

I love the series and am trying to read the manga (vol. 1) but am watching the anime (up to episode 8). I watched in a youtube video that Dark is crying and Risa’s grandmother is running towards him and then Dark leaves Risa and leaves her a note. What episode is that? He supposedly fell in love with her grandma. When does Risa find that out? What are the best Risa and Dark moments? That’s all the questions i have. Thanks if you answer!
Sorry, one more. How old do you think Dark looks like? He’s supposedly 300+ years old. He looks 16 to me.

I really dont know but you asked me what episode naruto transforming to sasuke was….Its episode 3
