Heeseung is your green flag boyfriend. You love him not because of his wealth or handsome face, but because of his sweet, kind, generous, and understanding nature. He gives you everything you want, not out of obligation, but because he genuinely loves making you happy.

Unlike other guys, he’s not overly possessive or controlling. He only gets jealous when there's a valid reason, but you always know how to calm him down—with a simple peck on his lips. He lets you wear whatever you want, as long as you’re comfortable, and he never stops you from hanging out with your friends, whether they’re male or female.

That’s why you love him so much—because of his genuine, respectful, and supportive nature.
