Starting July 2024 I'm (together with my friend) rating my read manhwa with 4 cathegories:
🍭 - sweetness
🎈- goofiness
🌶️- spiciness
🚩- red flag = self-explainatory.
Also since October 2025, we're adding a new rating category, based on characters characteristics and actions:
T/B - top/bottom
🟩 - a good guy
🟨 - a good guy with issues
🟧 - a bit suspicious guy, with psychotic tendencies, but not causing much harm
🟥 - a super suspicious guy, causing real harm
⬛ - a guy from the worst nightmares, that you wouldn't ever want to meet.
