hyung doesn't equal real/related brother in korea... I'm assuming you know that since you're reading manhwa. plain and simple it's NOT incest because they're not related, they're not step brothers currently, and they never thought of each other as actual brothers even when they were step brothers for 3 years. get better jokes
“Haesoo, it’s me, your brother, will you let me hit it again? <3”
