Shows like Nagi's Long Vacation

Nagi's curly hair is not her ideal so she spends a long time straightening it every day. Growing tired of it all and being triggered she becomes a hermit and goes for broke one day however. Not caring about anything includes leaving her hair messy. The disorganization seems to work for her. She is more relaxed, has more time and while she may not be pretty she actually is more relaxed and happy about her existence.
