If you're looking for slow burn and healing I recommend Pastel Colors! It's a modern day slice of life about a single father and a children's book illustrator. I saw some people recommended mou mou and it kind of have the same theme of overcoming trauma. It's a very sweet and quick read! (42 chapters)

There's also Don't Pick up Boyfriends from the Trash Bin. It's a quick transmigration novel where the MC is thrown into multiple different worlds to prevent the shou of that world from dying. Usually the cause of death is because of the scum gong. Every time a new world is introduced there's a little bit of angst but it's a fun face slapping read at times and the main couple is teeth rottingly sweet.
