What Happens When the Second Male Lead Powers Up Chapter 34 Discussion

Don't know what to say, the story is kinda interesting, but...

Chapter 1 - I will stay alive and figure out a way to get back, I will close off as much as possible to not get tied up with the main characters

Chapter 34 - Hopelessly tied up with the main characters and the royal family.

Been a while since I've seen a MC think of doing one thing and act totally different.

Maybe it is has a plot twist in the future where he and the old prince fused or have multiple personalities, because otherwise it made no sense at all.
