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.

Vocabulary

(Everyone)

全員(ぜんいん) means everyone or every member of a group, without exception.

(Friend)

友達(ともだち) means a friend or companion. Despite the suffix 達, it can refer to either one friend or several friends.

(All right)

大丈夫(だいじょうぶ) means all right, okay, safe, or no problem. It is a common word of reassurance.
