I think Sungjin’s love language is “Acts of Service". Because of this..

[A Thread]

sungjin blew the ramen before feeding it to dowoon

sungjin taking care of his son

wonpil was touched because sungjin gave him a guitar pick to throw into at the audience

sungjin driving just to find a strawberry milk for wonpil but there was only one left so they shared it

full vid :

sungjin gave his coffee for youngk because he realized that youngk wanted coffee than cola

sungjin knew that youngk couldn't eat spicy food so he tasted the food first to make sure youngk could eat it

sungjin fixing dowoon's hair

sungjin once said "I put day6 before myself"

when day6 ate together, sungjin was the one who prepared rice for his members, set the table, and washed the dishes

sometimes I forget that sungjin is actually younger than jae
