"We Are" is a slice-of-life drama, a drama that some may describe as "healing" content. The image that comes to mind when thinking about it, is a river, something that flows naturally and steady, without any huge obstacles, that is relaxing to watch. I am writing this so you don't go into "We Are" with the wrong expectations: it is a lot of silly fun at times, but it's more of a drama that simply wants to make you feel good.
Its whole plot can easily be summarized in a few words: two groups of friends connect with each other, go on small everyday adventures, and some of the friends fall in love with each other and have a lot of fun. So yes, no huge problems that stand in their way, instead you watch some great friends live their life and find their happiness along the way.
Now whether you will enjoy this drama or not depends very much on what you want to get out of it, what your expectations are. I started watching right before it had ended and binged all the episodes within a few days. I am the type of person who loves some fluffy content and who doesn't mind a more relaxed type of drama, and thus all of "We Are" very much appealed to me.
So what did I like? The positive portrayal of the friend group, the way they are so supportive of each other and their happiness. How even in their teasing you can see the fondness they feel for each other. Soft moments of understanding and romance that get mixed with the silly humour of some young guys who have known each other for some time. Some chaotic moments that end in more laughter. Great chemistry between the partners in each couple. The way that each couple feels different from each other: the teasing type of relationship, the lovey-dovey relationship, the slowly blooming type of relationship, a cat that falls in love with his puppy.

If you are the type of person who needs something positive in their life, something to lift you up when things get dark, I think this is the perfect type of drama for you. Just follow these friends along on their ride through university life, through their personal life, and it will give you a well deserved distraction, a massive boost of happiness.
