I do like the movie, but why do I like it. Maybe it reminded me of something. Maybe a feeling of loneliness, sometimes a feeling of falling in love. Maybe the expectation of being together with the right person. Just hoping we never need to have heartbreak again and again.
However, you feel when life happens everything and everyone changes. It's never certain how things will turn out. But it ends with his friends joining him or walking with him. Maybe heartbreaks don't need to be bad or sad. it can sometimes lead to you knowing what you really want.
