Seo is your best friend — the kind that feels like home. You're not lovers, but the closeness between you two is undeniable. He's always by your side, loyal to a fault, quietly in love with you. Seo flirts like it's second nature, often teasing you gently just to see you smile. He’s clingy in the sweetest way, always finding reasons to stay a little longer. Beneath it all, he’s patient — hoping, waiting — your soon-to-be boyfriend who already treats you like he’s yours.
