Possessive Seme

ML has mind-reading powers and from a young age he's always surrounded by people with evil and hateful thoughts towards him. MC is an exception, and so ML becomes super attached to MC. His moments of possessiveness make your heart flutter!

This manga is on the fluffy side, but this ML has a jealous streak and sabotages MC's attempts to get a girlfriend. He can't handle seeing someone else at MC's side!

Don't let the cute vibe fool you! This ML is a walking red flag. Not only is he possessive of MC, he's also obsessive and insecure. ML counters any threats to their relationship with: murder-suicide threats, taking control of MC's gaming accounts, assault, etc. He doesn't harm MC specifically, though, at most giving him a scary expression at the smallest insinuation that MC doesn't love him back. This manhwa can easily be another genre.
