*especially for the main leads

Hello, it's my first review for a BL drama, I hope you love it!
It will be quick in titles but long in descriptions since I'd like to refer to many things.

As a sum of my review; I think this series/drama will be a lead/guide for many other dramas. However, there are things that need to be changed/improved asap either. Here it's why:
+Great example for its production, character developments and casting (especially)
-But needs help with story details, character representations and scenario stages
*Still one of the bests of this year, so enjoy the show, honey!

+Character-ing
Well, I cannot say I'm so familiar and advanced-experienced with BL dramas but actually, real-life BL stories are not far away to me. (it as natural happens around us.) As far as I observe and believe, this is love above all; and the one harder to find, precious to keep. That's why I love how each character is unique/built differently--till the point they are and during the process we watched. In simple words, It's awesome that each one has changed, developed and the story base didn't fail while introducing them to us, unlike the other dramas putting labels like features-making leads noticeable for their sexual choices.
I always appreciate the diversity of couples in a drama when they are built as nicely as the lead couple.
Well, I actually love all, even though I personally had some doubtful thoughts about each, judged and questioned at certain points but it's understandable when you see them as the representation of types of relationships and the drama shows how personalities differ the relation, not sexes/genders.
Disappointingly, the development of the character Kinn wasn't enough or not shown enough; neither was their relationship with Porsche. It developed for Porsche, for his side, his character and his way. Not gonna give spoilers but trust issues are essential for every relationship, regardless of sexes and sexual relations; how deep it can go and how confusing/compelling it might lead the relationship is the deal for a drama, and I wanted to see this dilemma in the lead couple, how Porsche handles his first boyfriend and how they struggle but get over the trust issue.

+As the topic goes for the Story...
Just, in the beginning, I'd like to say that making a drama full of BL romance doesn't make it 'a great example of how homosexuality should be presented'. As we portray this in its own prepared environment, it will still be seen as alien, different, and far to the people-community-society. Not because we need the approval of all, but we in fact need to convey some essentials to the next generations who are risen by screens not parents anymore. And serving a BL lead couple within an environment where everyone is into far-less same relation, not helping. We should have seen some women characters or better -sisters of the characters, regardless of their sexual orientations, some heterosexual couples as friends or family quarters not just as parents. But well I think this is a common approach for BLs, yet this drama had great potential for this variety of relations and it would have been awesome.

As the continuation of the lead couple development conversation 1 paragraph above, additionally what I've mentioned there and as a reference to the right above paragraph about how we should portray this topic for the next generations; the drama should have been expressed with less sexuality then it tended to be seen. Not to say decreasing it, nope, if the director wants; just increase it; doesn't matter. But it should've been careful about how the sexual climaxes are built within the scenario. It got better in the last episodes when it's served with the action-based stages but still... It's understandable that characters are shaping their relations first with sexual tension when you think how hard it might be to find the right one/love for you as for many aspects in a community like that (even though it portrayed as it's like a piece of cake...)
-wanna add something real quick: for all characters in the drama, it's like they are all open to homosexual relationships since you know it's a BL drama and you expect that but actually if you look objectively, they are just how they should be, they found love first-then the gender comes... an important but hard to achieve tiny fine detail

+After story-sexuality is mentioned, the Production and Cast&Acting...
I guess this is the best part!
I mean this is why I watched actually.
The production with its cinematography, scenes, clothes, details, setting, colours, casting... just awesome, felt advanced-professional lead-high quality; a great example!
Not even a scene was dumb, despite the hard scenes like action and sex.

Last but not least... acting.
I'm speechless.
How perfect each actor suits their characters and how good they performed...
You can truly feel them, understand and question.
Especially the chemistry they all have... You know in some dramas you feel -the friend group's- their energy and that's what makes you closer with the drama as if you're there or you know them personally. If the acting wasn't good that and the chemistry I felt in the drama among them and between the actors and their characters, I don't think I'd keep up with that storyline.
And even if I decided to watch again in the future, as if I miss let's say, I'd do that just for the perfect acting. And of course, I'm planning to watch the other dramas of the actors.asap.

Enjoy the show!
