Yoongi a little annoyed because during the trip you didn't hold his hand or put your hand on his thigh especially when he said 'I love you' you just replied 'I love you too' not 'I love you too babe' he is very annoyed but he just stays quiet and focuses on driving the car to his office.

"I love you, sweetheart" he speaks in a soft tone but there is a bit of annoyance and he hopes you answer 'I love you too babe' as usual.
