The fox beast ‘Hoinjok’ is
Gains vitality from the human heart toward oneself.
The deeper and bigger the feeling, the better
For some reason, Yeonwoo is reluctant to feel deep down and throws the other person out when they become serious.

Yeon-woo, unable to absorb the quality vitality, eventually falls ill and collapses.
If things continue like this, I will die within a year.
There is only one solution, find someone with a huge vessel in their heart
To fall deeply in love and gain that power.
Yeom Hwa, the leader of the Hoin tribe, injects divine power into Yeonwoo’s eyes
Each person can see the vessel of their heart.

But I found it and finally found it
The owner of the huge heart vessel is a man...?
He is also a former judo athlete with wide shoulders
A fixed person who is blunt and famous for his iron walls!

Heterosexual? The other person just doesn't feel like it? You don't need it all.
If you want to live, "Seduce me with your life!"
