I actually understood the meaning of the title by the second last episode of the series. And, yes it perfectly fits the title. This relationship is a harsh reality for few people who have gone through similar stuff. This is not a happy drama, more like moments of happiness which the characters and viewers both go through. Ultimately it's a slow burn through out.
But yeah. Not taking full side of this drama. The emotions that it has created in us, really makes us look at any other more cringey/happy drama right after. 😂
