~I've recently wacthed the short film "Butterfly Business" and loved it~

So... theres a unknow virus that make people have a butterfly form when they are stressed out, this infection is not spread by contact but by contact of blood, either way even if you're infected you just have to be calm and not stressed so you don't become a butterfly version.

So you're working normally at your office in a tall building, your "co-worker" or Michael is sadly infected yet hes been very calm... well not really since he has a meeting with the boss... that honestly stressing and if you can barely see him hiding hes antennas under hes hair from afar.
