Kasuga Yuma and Hasegawa Itsuki, a same-sex couple, gained attention on social media for being “adorable” after giving an interview about the partnership declaration system for sexual minorities. One day, they received an offer to film a documentary capturing their cohabitation over 100 days. Wanting to promote greater understanding of homosexuality, Yuma accepts the proposal. However, at that time, Yuma and Itsuki had already broken up. Yuma persuades Itsuki, and the two decide to act as a loving couple in front of the camera. Unaware of the truth, documentary director Kayano Shiho is eager to capture them as they truly are… Yuma strives to be the perfect partner, while Itsuki feels suffocated by those expectations. What the camera captures, is it a happy everyday life, or a carefully constructed lie? A story unfolds, documenting 100 days where lies and true feelings intertwine!

This is not a BL which most of the fangirls will not get...

This is a slice of life, a failed relationship. Both characters have their "ideals", but both fail to recognize that they don't match with either their ideals nor views. Both characters are flawed, there is no idyll, no happy BL paradise where all problems are solved in 10 minutes of a 12 hours series. This is a depiction of the real world, when two people meet and get together of mostly selfish reasons, not knowing their partner, not knowing their partners desire. Something which should have been just a one night stand ended up in a relationship were it was only a question of time when it will fail.

The original was from a gay writer, who saldy already passed away. The filming set had an gay consulent and they really did put out a show, which is as realistic as it could be. And while many want only watch the happy BL fantasy and escape their boring lives, this is a realistc gay story without a happy end. But you can also say, both characters did have an happy end. Both characters grew and maybe both characters would hopefully not repeat the mistakes of the past.

This is one of the few shows which is about representation and after "Chosen Home" & "Life in Smokey Blue" japanese productions go where no other countries series ever go. Thailand is just mass-producing one crap BL after the next, Korea is a coin toss if the series is bad, decent or good. Taiwan has one of the most strictest protection laws in the world and same-sex marriage but sadly not enough output at least in the series space. And now Chinas production companies have recognized how much money can be made and they produce for foreign streaming services.
It's refreshing that japanese productions always brings diversity to the screen.

It's best said with a scene from the series, when "the boy" said:
"Those people who love watching guys making out, they only put us on a pedestal because we're two guys kissing. And they get all excited debating who's the top and who's the bottom." (not much guessing with thai ships)

Besides the MLs, the documentary crew are also important cast member and not just accessories. They also recognize that making a documentary is about the persons itself and not because they are gay. Production quality was very high, no complains from me. So of course, this is a recommendation to watch.

Edit: As it always is with MDL, nobody knows how many episodes the series has... So of the time of writing it stated 6... after searching online a source says 10. With that said, should we get more episodes I will edit the review and may change the rating as well.
2nd Edit: It seems MDL also decided it was the finale, so I'm very happy with the end. And yes, some relationship fail and that is just life...

One line from Itsuki stayed with me until the very end.

He compared himself to "a tropical fish that feels too hot even in the water where it is supposed to live."

I interpreted it as someone who isn't weak or broken, but simply cannot survive comfortably in the environment they were born into.

Sometimes leaving isn't running away.
Sometimes it's simply a survival strategy.

This drama isn't about deciding who was right or wrong.

Yuma loved Itsuki's freedom at first, but later realized he couldn't live with it.
Itsuki wanted to be accepted exactly as he was, and eventually realized that Yuma could never truly understand that part of him.

Neither of them was a bad person.
They simply reached a point where neither could compromise on what mattered most.

That made me think about relationships in general.

I don't believe living together depends on understanding everything about another person.
I think it depends on whether you can accept the parts you'll never fully understand.

Empathy is wonderful, but it isn't always possible.
Acceptance may be even more important.

The director said she wanted to create a film that could change the world.

Can a story really do that?

If people could accept differences instead of trying to erase them, perhaps there would be fewer conflicts.
But at the same time, I don't think the world is ever that simple.

I only hope that, someday, both Yuma and Itsuki will find someone who can accept them for who they are.

Not every love story ends happily.
Some simply leave us with questions that stay long after the credits roll.
