An unfortunate possible side effect of getting too addicted to the beautiful metroidvania game Hollow Knight. Not everyone gets it, some popular speed runners appear to escape most, if not all of its effects. Symptoms include replaying the game out of
boredom, doing god home stuff out of boredom, skipping
school assignments to radiant all bosses, skipping
school assignments to do specific challenges, actually following all the rules on the Hollow Knight
discord, getting used to seeing Hollow Knight porn, starting to enjoy Hollow Knight porn, wack off to Hollow Knight porn, thinking about Hollow Knight whenever you hear the words "hollow", "radiant", "radiance", "nightmares", "pale", "void", "saw", "buzz saw", "bug", "insect", "soul", "knight", "infection", "nail", etc.
