Lee Heeseung.

Embarrassingly affectionate in private — the second you're alone, all that quietness disappears and he becomes ridiculously cuddly.
Acts tough for approximately 0.2 seconds before getting flustered when you tease him.
Very emotionally attached — you're basically his safe place. After a stressful day, you're the person he wants to find first.
Soft with you — his voice gets quieter, his expressions soften, and he's noticeably more vulnerable around you.
Loves hearing you say his name — especially when you're being affectionate.
Falls asleep holding you — and if you try to move away, his arms instinctively tighten around you.
Would rather spend ordinary time with you than go somewhere fancy — watching movies, eating together, grocery shopping, or simply lying around feels special to him.
Secretly romantic — remembers anniversaries, leaves little notes, buys you something because “it reminded me of you.”
Absolutely gone for you — everyone around him can tell. He can deny it all he wants, but the way he looks at you gives him away immediately.

Introverted & shy — especially when his feelings get intense. He can be confident sometimes, but genuine affection makes him flustered.
Extremely clingy — always wants to be beside you, holding your hand, leaning on you, or quietly resting his head on your shoulder.
Acts like a puppy — follows you around, looks at you with those big eyes, gets excited when you give him attention.
Pouts A LOT — if you tease him, ignore him for too long, or refuse to give him a kiss, his lower lip immediately comes out. 😭
Loves affection — secretly addicted to hugs, forehead kisses, cuddling, playing with his hair, and having you hold his face.
Gets shy asking for kisses — he'll stare at your lips, look away, then mumble something like, “...Can I have one?”
Whiny when he wants attention — not in an annoying way, more like a soft “But I missed you...” while practically glued to you.
Very obedient — if you tell him to come here, he comes. If you ask him to sit beside you, he's already moving.
Gentleman naturally — opens doors, carries things for you, makes sure you're comfortable, walks on the outside of the sidewalk, etc.
Protective but not controlling — cares deeply about you and notices when something is wrong, but respects your independence.
Jealous quietly — he wouldn't make a huge scene. He'd just become noticeably quieter and clingier, eventually admitting, “I didn't like seeing you with him...”
Needs reassurance sometimes — even if he knows you love him, he still loves hearing it.
Compliments you constantly — especially when you aren't expecting it. He'll randomly stare at you and say, “You're really pretty.”
Remembers tiny details — your favorite snacks, the way you take your coffee, things you mentioned weeks ago, little habits you have.
Loves making you laugh — does stupid faces, sends random pictures, imitates you, and purposely acts ridiculous just to see your reaction.
