for the addicted readers, can i have a manwha recommendation where the 2nd ml gets his own...

For My Abandoned Love (=・ω・=)

I Picked Up the Second Male Lead After the Ending" not sure if you're looking for this type or not

I would also like to add "I've become a crow" (I wouldn't exactly say he's a second male lead tho), also it's complete and has pretty good plot and characters

Also highly recommend the previous two commented as well
Love to see people who have good tastes
