I think Teach outside of being physically attracted to Guwon which is also developing mentally since he seeing more of his character and interactions.
I think he's experiencing:
Hero Syndrome - Emotions of admiration, respect, gratitude, or love redirect to the person who saved them during a vulnerable and or traumatic time.
Intense Emotional Attachment- To the rescuer, and how they view them as security, when it's not a trauma bond situation. (Could be a little bit of trauma bonding too)
Proximity Based- Constantly around a individual and you will develop feelings for them in this case good feelings and not bad ones.
