Short answer
The main Sun red flags are confusing intensity with compatibility, creating drama when life gets calm, and needing constant attention; their warmth is real, but so is the sunburn.
Every birthday type has red flags, including yours. The useful question is which ones are habits you can talk about and which ones wear a relationship down. Yeon wrote the list. Bom made her add the green flags.

The red flags, one by one
🚩 Too much, too fast
What it looks like: Trip plans after date two, 'I have never felt like this' in week one.
What it usually means: Excitement, not depth yet. Let time catch up with the feelings.
🚩 Drama to feel alive
What it looks like: Small fights appear right when everything is going well.
What it usually means: Restlessness with calm. Worth naming early.
🚩 Oversharing, then pulling back
What it looks like: Deep confessions, then a cold week.
What it usually means: They felt exposed. Reassure without pushing.
🚩 Needing an audience
What it looks like: Moods depend on likes, reactions and attention.
What it usually means: Watch whether they can be content with a quiet night.


YeonIf every calm week ends in a fight, the fight is not about the dishes.
Green flags that balance it
- They make you feel celebrated, out loud and in public.
- They are generous with time, plans and praise.
- They forgive fast and do not hold grudges.

The Fire pattern
Fire red flags are about heat: too much too soon from the Sun, too much meaning read into small things by the Candle.
