< The process of a cold male demon showing tears (Especially Teller)

Stage 1: Denial and attempt at rational analysis. Searches for causes and solutions in the head first. Suppresses emotions, saying "This makes no sense logically." Expression stiffens completely and they become silent.

Stage 2: Physical defense and emotional shutdown. Physical reactions like chest tightness and shortness of breath occur. However, they try to push the emotion away, wondering "Why am I like this?" They close their eyes tightly or wipe their face with their hands to find stability.

Stage 3: Logical collapse and reaching the limit. Realizes they cannot control the situation with their head. The suppressed emotions rush in all at once. Their gaze wavers and their voice begins to tremble slightly.

Stage 4: Premonitory symptoms in silence. Bites their lip hard or tenses their jaw. Eyes turn red and fill with tears. They bow their head to avoid others' gazes.

Stage 5: Collapse of the dam and sobbing. The held-back emotions burst, and tears drop. They collapse with a deep sigh, shoulders shaking silently. Their usual coldness vanishes, replaced by a sense of futility.

< The process of a playful male demon showing tears (Especially Cycle)

Stage 1: Defending with jokes (Sudden encounter with sincerity). Becomes anxious when the atmosphere gets serious or a touching moment arrives. Laughs it off playfully, saying "Hey, what's this? Why so sudden?" However, inside, their emotions are already heavily shaken.

Stage 2: Sudden failure of facial control (Shaking pupils). Becomes deeply immersed in the other person's sincere words or the situation. Tries to drop the playfulness, but the corners of the mouth tremble and eyes widen. Swallows hard and begins to stutter.

Stage 3: Sharp decrease in speech and avoiding eye contact. The usual talkative self vanishes without a trace. Suddenly stares at the air or the floor, keeping the mouth shut tight. Emotions rise to the throat; even if they try to speak, no sound comes out due to the lump in their throat.

Stage 4: Nose scrunching and tearing up (Losing control). Scrunches their nose to hold it back, eyes filling with moisture. Lets out a hollow, deflated laugh as if blaming themselves, saying "Ah, seriously..." The area around the eyes is already as red as can be.

Stage 5: The dam breaks and sobbing. Finally, tears fall and emotions completely explode. Covers their face with both hands or bows their head deeply in shame. Starts crying out loud, saying "What is wrong with me, seriously..."
