This drama is a kaleidoscope of failed relationships and call me a cynic but I'm not seeing a bright future for most of this drama's couples:
-Yu Jung and her lazy ass husband finally talked it out and have delved into role playing games to spice things up, but watch them get bored in a couple of years again. The husband will be the first because he is just lazy by nature and takes his wife for granted. And the wife needs constant affirmation of their love.

-FL's spoiled brat of a sister just didn't give me the vibe that she truly loves the guy, she just goes with the flow in life. A NEET and a minimal wage worker, they are a staple divorce statistics example, so often stories such as these happen. Since they don't even know each other well or what they want to do with their life I think in a couple of years she's gonna start blaming the guy for ruining her life and gonna end up a divorcee with two kids, continuing living off of her relatives. If I were FL I would have given her an earful and kicked her out of the "bird's nest" long ago to get a taste of real life. Or at the very least made her pay rent. I really dislike lazy loafers like these, have seen them in real life and they just never learn to live on their own due to continued coddling.

-U-Ri and CEO...just why and how the ef? I don't even think CEO really fell in love with U-Ri, no chemistry whatsoever. He just didn't want to end up alone in his age and used her puppy love to his benefit. Too bad his ex wife didn't want to get back together with him, would have been a better fit. I don't know what else to say besides it being cringe.

-That bitchy bride friend of FL's is gonna get divorced in a couple of years as well. Pressured an unready guy into marriage, yeah, that's gonna end well.

-The chicken sh*it of an ex his current gf - not gonna happen. At this rate the guy is going to end up forever alone, he really needs to dial himself down by a lot.

-ML's ex and her husband - not really seeing it either. She clearly didn't know what she wanted and gonna question and beat herself up until her husband will get sick of it.

-ML and FL...they will probably be ok? ML kinda half-assed his confession, but FL considerately gave him slack. ML really struggled to convey his feelings until the very last, but judging by his behaviour in the end he seemed to have overcome it, he became all lovey dovey with her. They were quite cute in the end. And FL is not going to ditch ML, because where else will she find a guy who likes her no matter all the embarassing stuff she constantly gets herself into. Personally, I think the lead couple was the most natural in development and healthiest of all of this drama's relationships. Their bonding through similar ordeal allowed them to really get to know and understand each other, which I can't say for many of the other couples of this drama.

Overall, a 7/10 from me. I really loved YIN's performance, she really carried the show and managed to pull off various aspects of her character, ranging from really embarassing ones to very mature ones, with effortless grace. I can imagine it must have been difficult though, because her character had to stay likeable while being very flawed.
And some of the show's dialogues were real gems, full of witty banter and meaningful one liners.
But still:
-1 point for cringey U-Ri and CEO couple.
-1 point for trainwreck of a shotgun couple.
-1 point for too much screen time and tears wasted on Mr. Trash.
