Crescentvn said: I think that's not Lily that got picked on, but rather Sakuya talked about her own experience. And we all know Rem wants Letty to play with more.
You could be right. There's no actual subject in Sakuya's comment about who got picked on; it could be her or Lily. However, the previous sentence is definitely about Lily being the meddler. It could be that Sakuya befriended her to protect her from getting picked on.
ijimeru = pick on =/= ijiru ijiru = play with : toy with : tamper with : fiddle around with. Lily was toying with Sakuya.
