In the first post, T.O.P uploaded a black and white photo of his sister, holding baby T.O.P with a caption, "with my sister." You can see the striking similarity between his sister and T.O.P!
In the second photo, young T.O.P is wearing hanbok (Korean traditional clothing), running toward his mom. In the second cut, baby T.O.P is giving his mom a kiss on the cheek. The singer wrote, "I love you, mom" as a caption. Such a good son!
