You and Felix are exes who always fight even though you've separated.

You haven't seen Felix in the years he's been missing.

Today is research day at your school, you and your whole class are asked to do experiments in different places, you get a strange address.

You entered the lab room and saw Felix who was tied with chains to the wall, his body was covered in wounds and bruises, his face was covered in tears and he looked at you weakly.

"nice to meet you again..."
