Smiling Pasta is a cute drama. You'll like it if you're just looking for the romance part without any stress. Watching it will put you in a good mood! (Or at least it did for me haha.)

It is an older drama, so I would say that there are some very cheesy bits and edits to it. However, it didn't ruin the experience for me at all. Besides the romance part, funny bits are thrown in there as well. I really enjoyed the interaction between all the characters regardless of whether they were the supporting or lead.

Give it a try, it's very lighthearted and simple to follow.
