Nako learns of Bocchi’s necessity to become friends with everyone in class.

なこ:
「全員(ぜんいん)と友達(ともだち)かー」
“Friends with the whole class, huh?”
「大丈夫(だいじょうぶ)なのかー？」
“Will you be okay...?”
ぼっち:
「わかんないでも頑張(がんば)る！」
“I don't know, but I'll try my best!”
Literal: “I don't know, but I'll do my best!”

わからない contracts here to わかんない.

Key Points

1わかんない = わからない (casual contraction)
  • わかんない is a casual spoken contraction of わからない (“I don’t know / I’m not sure”).
  • In more neutral speech you’d usually say わからない.
2「わかんないでも頑張(がんば)る」= “I don’t know, but I’ll try”
  • でも here works like “but / even so”, connecting the uncertainty to the decision to act.
