Both are short (10 eps) D+ dramas where the ML is a bodyguard with a past. The FL is a public person of some importance. There might be some cold-hearted romantic development with the lead characters pretending nothing is happening while it is happening.

Hopefully, Red Swan does get a definitive ending.

There are good fighting scenes, lots of SFX and a very interesting soundtrack for both dramas. In terms of plot, they might not have all that much similar, but in terms of cool effects and explosive scenes... they might. IRIS might be more action-oriented, Red Swan seems to have some side-plots too.

ML has a hidden revenge agenda against people responsible for the death of someone he cherishes. In order to get that revenge, he has to join an organisation with its own problems.

Some good action scenes again, for both dramas - hopefully Red Swan doesn't have an open ending.

A woman of mystery and a bodyguard with a secret agenda in both dramas. Some good action scenes in both dramas. The ML acts and looks cool while the FL has the cold-blooded reasoning. There is a streak of romance in both dramas.

It remains to be seen how Red Swan gets to its ending and if it's satisfactory for the story it tries to tell.

The initial feeling is kind of similar - an older cast who do their own revenge-remembrance-redemption thing, young heroes finding their place in the world, maybe there'll be some tragedy, lots of action scenes. And there's a promise of sworn brothers in Hot Blooded, just like there is in WBDS.

Both seem to be gritty, almost noiresque stories of police lives. Leads are established and amazing actors, there is a thread of tension throughout each episode (Connection is just beginning but I think it'll be keeping up the pressure).

This is it - go back and change the past to save the one you love. Both stories involve time travel (or at least astral projection) where one of them travels into the past in order to make some changes to save the other one. Both have a very wholesome feeling to them.

The premise is very similar with both dramas. Lovely Runner is just starting, here's hoping it reaches a HEA (or at least a satisfying end).

Superheroes... superheroes as far as the eye can see. Only some of them aren't actually superheroes, it's just the drama showing them as if they almost have superpowers.

The general feeling is the same though.

One day, the MLs of these dramas happen to make a small mistake, and from that, everything in their respective lives changes. They keep making choices, some smart and some not so much, and depending on their respective luck, things continue happening and changing their whole lives around.

Setting - both happen in legal 'verse, one including detectives, the other the justice system, both include crimes, both try very hard to be noir.

Both dramas are action dramas, the characters aren't too black and white, good guys lose at times and bad guys win at times, and then the action goes the other way around.

Great action sequences in both dramas, great acting, very good leads in both of them.

Excluding the romance in TOTNT, the short presentation of YYH sounds eerily similar to the basic plot of the other drama. I haven't watched the anime, read the manga or plan to watch the drama for YYH, but still... "working for boatmen of afterlife" - check, friends with the (friendly) Death Gods - check... Sounds like at least some of the premises are similar.

Amazing chemistry between the leads. Awesome cinematography. Great music.

Differences: unequivocal (and long) HEA for one of the dramas.
