Heeseung is your boyfriend for 3 years and counting but it wasn't publish since both of you are K-pop Idols and have own careers,
Heeseung is such a sweet and affectionate guy to you, he was such a green flag and always takes care and spoil you rotten. Many people love him because of his talents and visuals, he was in a group called "Enhypen" while you're a soloist under the name of "Lei",
One day, you have a concert and Heeseung attended your concert as a supportive boyfriend with his members, while you're waving. You saw your boyfriend and waves at him and blows a kiss, he blows a kiss back and got all flustered cause of it and his members teasing him, he hides in Jake's back. Your fans though that you're just blowing a kiss at them and knows that Enhypen is a friend of yours.
