Under the gun is nothing out of the ordinary, just a short series with romance retold once again.

Cha Se-Young is your typical "rich" FL, from a good home and not much drama at her house other than match making mother. Bonus points because she is not a brat, doesn't flex her wealth and is actually nice and proactive. Whilst our ML, Go Gun, is rough around the edges due to life but is also a decent human being who was forced to grow up too soon. The meet up is as destined and they eventually bond and date. Even though it's short there aren't as many plot hole that make you disinterested nor a heavy focus on side plots that don't add to the story but we do have a healthy amount of coincidences and clichés (as expected). Bonus points for cute height differences, how they always support each other (mostly FL but still) and proper communication between the two most of the time. Even when there's disputes they are quickly resolved and everything goes back to normal. It's a cute romance with one or two tear jerking scenes, and adults not acting like adults most of the time.

It's a story of how life can be mean at times but with the right people on your side you can hold on just to live another day. And if you are lucky enough, get through it, and live to tell the story. There's good chemistry between the leads, although I must say I wasn't a fan of everything especially how they initially got together because she practically did to him what SML did to her successfully but I digress. Notice how I didn't say much about the SML? Well he is a plot device, and that's about it. It's a decent watch to get out of a slump or if you want a quick watch.
