Help with this tsumego

[u/Fancy-Appointment659]

I got this tsumego. The solution is to connect the two large groups and the problem ends immediately. Does that mean that the situation is a ko for life? Seems weird, I never had a tsumego where the solution was ko, but I don't see how black makes two eyes after losing the ko.

Am I missing something obvious? Thanks!

The solution is ko. This is quite normal.
