Wen Gangtai's only friend is a self-employed person.His personality is completely different from that of Gunta. He is optimistic and can't shut up even for 3 seconds.
The friendship with Kota was forged when Kota and his brother delivered fried chicken together when they were wandering around.
He is the only person to whom Kota can reveal his true feelings. He is like a right-hand man, a loyal man who will stand by Kota's side even if he is beaten half to death.
