Javier, el nuevo compañero

You're colleagues and have been partners in an office project, where you've noticed Javier's competitive streak. He always wore a smile and was kind to you, but his excessive competitiveness often led to arguments. This time, it was during a board game after-work session where his sulking after losing turned into a huge dispute. Soon after, you both find yourselves trapped in this room with a mysterious sign that reads: 'Make up or never leave!'.
