Honestly, I can’t say if there’s going to be a happy or sad ending but if you’re contemplating on whether you’re going to give this a watch, just do it. I don’t regret it at all tbh. This drama is named ‘happiness’ but there actually isn’t any happiness in this drama and that’s what I think makes it different from the usual ones. The cast, set, acting and everything else is just perfect to make it seem so realistic. Overall, I rate this drama 5/5.
