Includes seme that are playboys, cheat, take the Uke for granted, treat the uke as only a friend with benefits or shows limited affection toward uke. This also includes seme that think the uke will always be by their side until they’re not or doesn't see uke as a love interest. Overall, angsty stories.
Also, some of these ML are actually not that bad but if our MC is being treated poorly then I’ll add it.
List of the stories I've read where we'll be left with a single 'Second lead syndrome'
Salute to these characters for they have proved their worth. I wish them all the best.
Note: Some are caught in a cycle relationship- ex: seme loves uke, but uke likes someone which is currently in love with seme. Sorry for not sticking but tbh it's the same for me lol. In the end there will be a pitiful character who'll be left behind
