Second lead syndrome

It's a dream come true having reincarnated into a historical romance novel I once read in my past life. But I'm not the main character. And watching with my own eyes the second male lead persistently trying to gain the female lead's attention with all his might made me want to cry. He deserved better! The poor second male lead deserved an entire universe! Not just an ignorant, obnoxious heroine, but the entire world, alright?! If no one else wants him, I'll have him, please!
