My Dearest Nemesis

Both are GAMES + ROMCOM Kdramas,
and Enemies-to-Lovers Noona Romances.

In Lucky Romance ML & FL both work in Game Industry creating games.

In My Dearest Nemesis ML & FL both met Online only playing a game when younger and meet again in real life years later.

Both dramas tell stories about complicated relationships. "My Dearest Nemesis" seems to be about people getting over bad things that happened to them and growing as people. "My Sweet Mobster" seems to be about a man trying to be good after being bad. So, if you like shows with people who have old relationships and change a lot, or if you like shows about childhood relationship, you might like both of these dramas.
