CAUSATION: Beyond this point readers are warned that the following contains some mature, petty content with dramatic language, so I don't need no hateration, holleration in this dancery!

Personally, I was so disappointed with this ending that I was forced to make my first review to save others. Honestly, this drama had some quotable moments before shit hit the fan towards the end.

 I enjoyed:
-BEST OTS of 2017 better than Goblin and DOTS put together.
-I love the consistency of the GOOD acting skills from ALL the cast members even the supporting,
-Filming cuts and narrating from both leading allowing the audience to gain different perspectives. And increased your understanding of the characters actions and emotions (I think it humanised a lot of characters that appeared selfish).
-the beginning with very addicting because it seemed to have an adult tone with relative beautifully written plots.
-At first I appreciated the balance between the cheesy couple moments with the reflective tone.
-this drama had a lot of potential as it approached adult relationships with characters responding close (comparing to with general kdrama standards) to realistic reactions.  
-Every couple had me in my feelings with the chemistry in the relationship being natural in some and others realistically awkwardly progressing (again believable pacing ).
-This was the first drama that EMPOWERED me to venture outside me shallow preferences.
-I was grateful for REAL kisses and make-out scenes.
-No last minute kiss scenes (waiting for 525600 minutes).
-The writers didn't complicate nor prolong meet ques or plot-lines (to an extent).
-I never skipped because the dialogue and the pace of every episode was synced.
-interesting story lines.
-The filming was on POINT! Especially the shots and angles because they added to the actors performances,  made certain scenes more intense and kept it simple avoiding distracting the viewers (camera focus was clear as iPhone users).

-I would suggest this drama for those seeking a light hearted drama filler.  

Disliked:
-I took it too seriously and I got more invested as it aired.
-When shit hit the fan and the last script scenes went with it.
-Went from unique drama to basic kdrama.
-The writer thought it was a laugh 'ticking' me with  unnecessary story-lines that just ended up back square one.
-Made me root for hopelessness!
-Sacrificed a LOT of the casts character's development and defining decides for certain character's personal growth. (.e.g.  Yoon Ji Ho's traits went from Lovely Sam soon Kim Sam Soon to Goong- Shin Chaekyung).
-Unexplained character possessions of all the main cast- near the end had them making out of character decisions.
-The supporting cast vanished (deleted my bae #HotnessInPink).
-Limited episodes made some characters seem neglected because we didn't have enough time to explore their backgrounds, resulting in certain relationships only scratching the surface.
-Cliche BS Rom-con moral of the story ''love conqueror all''.
-Stops addressing the topic ''what happens to couples when love is not enough''.
-Decided to be messy and take notes from 'How I met your mother' with a CERTAIN couple.
-Questionable introduced plots could have added depth to story-lines but were abandoned or water-down.
-Contains contradictory  messages comparing them to previous dialogues and the narratives points.

No, I will not re-watch this kdrama and I'm done with tvN thanks for another misleading journey towards a filler fluffy ending.
