Good Feeling
Feeling Good, Feels Good
expression, い adjective
When you have a "feeling" (気持ち) that is いい (that means "good" by the way), you have a good feeling.
The reading comes from the vocab word 気持ち, so if you know that (or the vocab words 気 and 持ち) you should be A-okay on this one. Maybe even feeling good about it?
