Otome Isekai is a sub-genre of Isekai where the main character(s) are in some way transported to another world that resembles an otome game...

It is essentially the girly version of the modern shounen isekai that goes in the direction of female wish fulfillment. Instead of stuck in an action game, she's stuck in a romance novel or romance game. It is almost always "died and reborn there" rather than the sort of "stuck" we see in Sword Art Online or the "teleported" we saw in the 90s.

Here I put some of the romance manhwas that I love and some even have a few similarities, types like Historical (Duke/Duchess, Prince/Princess, Empress/Emperor, King/Queen, Lady), Villainess/Villains, Family, Magic, and a few modern ones...

𝐏𝐥𝐞𝐚𝐬𝐞 𝐫𝐞𝐚𝐝 𝐭𝐡𝐞 𝐟𝐨𝐥𝐥𝐨𝐰𝐢𝐧𝐠 𝐛𝐮𝐥𝐥𝐞𝐭𝐬 𝐛𝐞𝐥𝐨𝐰 𝐛𝐞𝐟𝐨𝐫𝐞 𝐩𝐫𝐨𝐜𝐞𝐞𝐝𝐢𝐧𝐠:
💭 This is ranked (as much as possible) by the male white-haired character's level of "male leadness" and since this is more or less a stack of romance manhwas, the criteria we're going to go with is that they should be the main love interest or endgame for the female lead.
💭 Therefore, there will actually be manhwas listed here that features the white-haired character as a second/third/etc. lead, support role, or in general just doesn't apply to the criteria we're following above. Don't worry as I'll be very specific about it as possible to prepare you for the heartbreak.
💭 The MLs' name would also be mentioned. The manhwa's synopsis would also be added right after so if you don't want to see any of that, I would recommend switching to tile/seasonal view.

[ above all else,, i really just need a compilation list of white-haired male leads for research purposes and not because i have a personal bias for silver mls (i do), 'tis all :> pls ignore me thank u (o_ _)ノ彡☆ ]

Don't let their cotton candy hair fool you! Despite their clumsy antics and second-hand embarrassing decisions, this FL might just be the type you don't want to mess with.

Recommendations for series that include love interests whose love, admiration, and devotion is so strong that it is expressed as an excessive obsession and possessiveness. Sometimes using extreme violence or brutality as an outlet for their emotions [Though the latter part is not the case for ALL love interests in the list]

(Copy n pasted throughout all my yandere stacks)
This list includes everything from mushy cutesy to ‘oh god I'm on a watchlist now’ so scroll with precaution.

There are two requirements for this list:
-The yandere needs to take up ATLEAST 1/5 screentime (if they don't take up half then ill put this note: yandere is a side character)
-no porn unless its gore or psychological horror

I've checked everything so even if the yandereness doesn't show at first trust that it's coming.

For any stories where the protagonist and love interest are already together, or get together quickly, or if they resolve their issues/misunderstandings quickly so they can deal with the main issues within the story together.

This will also include stories where the protagonist isn't denser than concrete and will admit to their feelings relatively quickly. We stan protagonists that proactively go after their love interests.

This stack is for anyone who has reached the point where they can't do angst, and the idea of more miscommunication and misunderstandings makes them want to throw their phone/tablet/laptop/PC off the nearest cliff. All we want to see is love and happiness in our couples, and root for them!

Who cares if he fell first or not? He definitely fell harder!

[ TL;DR : Manhwas where the male lead is totally smitten with the FL. I try to find ones that slightly border on the psycho level but is not totally psycho ]

[ Has red flag levels with four categories: (1) SIMP, (2) LOWKEY CRAY, (3) CRAAAZY, and (4) HE PUTS THE YEAH IN YANDERE, all with ranging sub-categories. The number one category (simp) is still a red flag but the tamest with the fourth category being a major red flag. If the ML happened to not fit in within this categories, he'd be rated GREEN as in green flag. Got it? Good! ]
