Male lead has to escape the sibling-zone to be with the female lead

The female lead thinks of the male lead as a brother, but he loves her. Eventually he gets out of it and they get together. Maybe during him trying to get out of the sibling zone, she likes someone else.

That sounds kind of like Pinocchio, but there is mutual affection with hate type of relationship going on between them. You would need to get past the first 3 episodes that are weird. It gets way better later on.

• +1 for Pinocchio (fake-uncle-zone!)
• Something in the Rain
• Healer (there's a funny line where she actually says he's like a brother to her)
• I Hear Your Voice
• Hwarang
• I Need Romance 3 (the FL looked after the ML when they were little, and as an adult she views him as an annoying little brother)

• Pinocchio
• Devil beside you
• I love u love u love I
