Seungmin plays the role of a reliable big brother, but since he wanted to have a lot of younger members to tease and there is only I.N, he also likes teasing him a lot. Since they are both the maknaes and the vocalists of the group, they understand each other more. They share the same goals and worries, and can have serious talks. In 2021, Seungmin took I.N to his vocal teacher[1], Voice Tuning, which made them bond more deeply. Their vocal lessons are special and funny moments together.[2]
