Content warnings: none I can think of

Overall: A slower paced (too slow in my opinion) series dealing with a realistic problem.

What I Liked
- A more realistic reason for the drama
- Supportive siblings
- Lack of evil girlfriend/ex-girlfriend/stalker "fan"
- Focused on 1 couple* instead of a billion (slight exaggeration) couples

Room For Improvement
- 4 year gap: I really dislike time gaps where 1 person makes a unilateral decision and the other person is miserable for years and years supposedly for their own good, ugh.
- Number of flashbacks/flashforwards: it takes me out of the story and this had quite a few of time hops especially via flashbacks. The whole 7th episode was a flashback, it felt like filler.
- Lack of doctor/patient confidentiality: I think the sister could have talked to Nut about Phob instead of his doctor
- *Not being clear about the brother & Tar's relationship until episode 6: just a few romantic moments would have made this clear earlier. I would have liked their relationship to be more developed.
- Pacing felt too slow to me: I watched this on at least 1.5 (or more) speed and I think it would have been better as 6 episodes, maybe even 5.
- The ending: was okay, I generally don't like cliffhangers and I don't think it had the impact it should have had because of the lack of a developed romantic relationship. I would watch a 2nd season though.

I skipped ahead from ep 5 to the end because I was worried and fyi it is not a tragic ending. 
Watch past the credits of each episode as there are side stories/interviews with the cast/director. 
I think I'm being a bit generous with 7.5 as I really had to push myself to finish all 8 episodes.
