need help finding a regression? manhwa

Hey everyone so lately I've been constantly thinking of this one manhwa that I want to re-read again but I can't seem to recall the title for the life of me ╥﹏╥

The mc is a mom that neglected her son after marriage because she had really bad post-partum depression and was kinda ignored by her husband (can't remember why tho). She felt like now everyone was defining her by her role as a mom and forgetting about her own self. So she just went around partying and not fulfilling her role as a parent. The whole plot is that she wants to repair her relationship with her son mainly and we see like the different stages of their relationship improving (and with the dad too, I think? ╮(￣▽￣)╭). To be honest I don't remember what made her change her mind like did she die with regrets and goes back in time or just realize her shitty attitude on her own??? But I just remember loving how the son feelings were depicted like he wants to believe in his mom but can't help but be doubtful/scared of her sudden change in behavior.

If you have any idea of what the title of this manhwa might be I'd really appreciate your help! (づ￣ ³￣)づ
