SungGyu: Whenever a member feels very tired, the rest of the members will sense it and also keep quiet, so that the tired member will feel better in a quieter place.
SungGyu: Since we (infinite) are all adults now, sometimes we will gather a drink a little bit of beer. It will also be the time where we
confess things like "Ah i don't like you because of ...." and "I think sometimes you are a bit too...". We will tell each other things we are dissatisfied with. We will not keep what we want to say in our heart. This is our way to make us closer, make us more bonded. By telling each other what we are dissatisfied with. By doing this, we feel that we become more closer and bonded.
