〜でも~de mo
even in a situation
Use 「〜でも」 after a noun to stress that an action continues even in a difficult or unusual situation.
How it works

Look at the two arrows: they study on ordinary days and still study on busy days.

Include even a situation where doing it is difficult, stressing that it happens even then.

Attach 「でも」 to a noun. 「忙しい日」 is a noun phrase, so 「でも」 follows the whole phrase.

The action stays the same even in special circumstances. Use this to emphasize keeping something up.

「一人で」 simply says you attend alone; 「一人でも」 stresses that you are willing to attend even without anyone to go with.
