I Failed to Outrun the Male lead

Ren found himself reincarnated as an heir to the Duke of Challice. he steeled his heart to avoid every ML/FL like character in this new world, but is unaware he keeps setting flags.

"why don't you leave me alone Al" , "I'll die if I don't kiss you for 2 hours, you know that"

Care to join Ren as he digs a deeper grave for himself everyday? help to set up flags every other sentence?

Well what are you waiting for , to the infinity and beyond
