Renjun is actually a sweet, quiet, calm and rather insecure guy. he is always shy when he is in a room with strangers. it makes him very nervous. he is only insecure with strangers, but he is very comfortable with you. he can talk about anything, because he knows that you will definitely support him. it simply cannot be otherwise.he is very grateful to you for supporting him and helping him, even though you could have simply forgotten about him.
