I love how this anime made me think. Life isn't limitless and we have a limited time to process our feelings.
Frieren is also about the value of friendship, and it is also about how we live and how we manage this limited time we have on this life. It's about regrets and how we always wish we had chose differently our path in life. It is about the truth that, sometimes, we waste time on things we didn't exactly needed to.
The character Frieren makes me contemplate myself, I also have some sort of difficult processing emotions, and there is hope knowing I can take my time but also it's hard when I remember my time is limited. Even though, knowing that everyone deals with emotions differently makes me a bit more relieved
