Interdimensional Love drama?

hellow everyone, What are some good dramas that portray romance between the leads who do not belong to the same world? 

what i am looking for:

1. the romantic leads should completely belong to different worlds. not both of the same but ended up differently due to past events. or both of the same world accidentally travelled to another world.  ( ex: lost romance shows that the FL ended up with the Real world ML, that's not what i seeking, both Leads should definitely belong to different worlds)
2. it can be of any type
   1. Two different universes (example : king the eternal monarch)
   2. One lead is from real world, another is from comic/fiction/novel/game ( w:two worlds)
   3. from different planets ( example: the love from another star) :but im not exactly looking for this because there won't be much transmigration in "reaching" each other, because probably one of the leads will have advanced technology
   4. Huge time gap, like centuries separating the leads. and they don't meet because of them is immortal, they meet because one of them gets transported to the other's era
   5. both the leads are from different fictions (Night of Love With You)
   6. One lead is from a demonic/angelic world, another is human.

what im not looking for :

1. rebirth scenario 
2. time separating them, but they meet in the same timeline (because one of the leads in immortal
3. both leads from the same universe get accidentally transferred to another universe (Serendipity )
4. leads end up with the counter-part of the love interest in their own world

any language or length of series will do

To the best of my memory, all of these have the leads together at the end with what you specified. Some have more than one season, so that ending is at the end of the last season.

One of the leads is from the real world, the other from a comic book, novel, game, or tv show:

• Pop Out Boy! 
• A Puppetry 
• Affairs of a Drama Queen 
• Am I the Queen Mother Today (movie)
• Bossy Husband Who Loved Me 
• Broken Dimension Love 
• I Want to Live to the Finale 
• It's Nothing More Than Love 
• King Is Not Easy (in the last few episodes, it's revealed that the FL is a writer, ML is her character and he comes to her world and stays)
• Love & the Emperor 
• Metaverse (Possibly? I'm not sure if he's the character or not, but he seems to be)
• My Poison Lover 
• My Villain Husband (if you watch the bonus epilogue)
• Please Don’t Spoil Me 
• The Queen of Attack 
• The Queen System 
• White Fox Prince, Please Behave 

One of the leads is from modern day, the other from ancient history and one of them time-travels to the other's time:

• Faith 
• Live Up to Your Name 
• Must You Go? (The ending is open but can be seen as happy, depending on your interpretation)
• My Only Love Song 
• Queen In Hyun's Man 
• Tinted With You 
• Childe Xie's Wine 
• Cinderella Chef 
• Foodie Queen 
• Gourmet in Tang Dynasty open ending for another season but FL is still in the past with the ML when it ends.
• Guyuan Imperial College 
• Large Queen 
• Love for Two Lives 
• My Fantastic Mrs Right 
• Princess at Large 
• The Eternal Love 
• Ashi Girl 

One of the leads is from earth, the other is an alien:

• Be My Cat 
• His Royal Highness Spoils Me 
• Let's Shake It! 
• Love at First Taste 
• My Girlfriend Is an Alien 

One of the leads is human, the other a god/deity or angel:

• Moonlight Romance 
• Rainless Love in a Godless Land (also has parallel worlds)
• The Ghost Bride 
• Angel's Last Mission: Love 
• Doom at Your Service
  
• Secret Love (2 of the episodes)
• Soul Plate 
• Dear Herbal Lord 
• Love of Thousand Years (ending is a bit ambiguous, but it seems to be happy and the leads are together)
• Ms. Cupid in Love 
• Rain Lover 

One of the leads is from earth, the other a parallel world:

• The Heavenly Idol 
• Train 
• My Dear Brothers (it's a bit unclear if it's him or a double at the end, but there's a bonus scene that reveals it is indeed him.)
• Oh! My Emperor (There's two versions of the ML, one in the real world, the other in the parallel and the FL ends up with the parallel one who comes over to her world at the end.)
• Love Better Than Immortality (It's kind of a parallel world, kind of fictional, kind of time travel.)
