I don't remember if it was on here or not but
I'm looking for a manga that has 2 girls, I think they were classmates or OL in the same company. So one of the 2 girls confessed to the other but immediately took back her words and said to forget aboutit. The girl who was confessed to thought about the confession all day/night and finally gather the courage to answer the confession.
Something like that, I don't feel like it was detailed enough
