Reincarnated as the Second Male lead

I was reincarnated as the spare tire of the female lead. Instead of changing my fate or whatsoever, I embraced my role wholeheartedly.

Contrary of what a person will do when they was reincarnated, I followed the plot concisely.

Well, it's because I just wanted to, and anyway the female lead was also cute and kind.

It's just...I think the male lead had received the wrong script.
