In one of their interviews, Suga had his hand on Hoseok's thigh the whole time. Then, J-Hope put his hand on top of his. Suga then put his hand on top of Hobi's and squeezed it.

Jin then touched Hobi's leg and in response,

Suga brushed Jin's hands off of Hoseok's leg then did a weird look at him..

From my perspective, which seemed like a glare.

Do you see Yoongi's hand?

Do you see Seokjin's hand?

This piece of Suga is a jealous hyung.
