He isn’t strict, but he does get genuinely disappointed whenever the child crosses a boundary or behaves irresponsibly.
It’s the weekend, and everyone in the family has taken the day off to enjoy time together. Guest, however, slips away to the garden as usual. He’s discovered a new source of excitement—the tall apple tree he loves to climb. His adults have warned and even forbidden it, but he’s far too mischievous to take their rules seriously
After successfully sneaking out while the adults are distracted with their own tasks—certain he’s still upstairs watching TV—Guest slips into the backyard. Confident no one will notice, he makes his way to the apple tree he’s strictly forbidden to climb and starts pulling himself up its branches
Passing by, he decided to check on his boy for a moment. Hearing the TV, he assumed Guest was still watching happily, but when he opened the door, the room was empty—only the TV running. Knowing how mischievous Guest can be, he searched the house, then stepped outside. In the backyard, he finally spotted the child perched on the apple tree like a little monkey. He sighed like an exasperated parent Guest! What did we talk about? Climbing trees is dangerous—come down right now.. his voice gentle but still frim
He pouts, just like any bratty kid, then settles on the branch even more comfortably Dada... come on... I’m already up here, and I’m only sitting… what’s so bad about that? His voice turns a little whiny, full of stubborn protest
He just shakes his head, knowing it’s always like this when raising probably the most stubborn kid in the world Guest… what’s bad about this is that you might fall and get hurt, and you don’t realize it but Letting children climb trees is considered risky, and we clearly forbade you from doing it. Being naughty and disobedient is also a bad thing.If you understand why what you’re doing is bad, come down. His voice grows firm or I'll call your father or Jiji, you know both of them are here today.. he gives that warning always seems to get to Guest effectively
Dadaa.... He whines, clearly not wanting to get down anytime soon
He was looking for his husband and his baby, who should have been in his room, when he noticed the commotion in the backyard. He sighed, already resigned to dealing with a stubborn little brat, and walked over to them What's this… baby boy, what are you doing up here like a little monkey? Do you want to fall and break some bones? If not Better get down… we talked about this not long ago.. His voice is gentle and playful
He pouts even harder and looks away stubbornly, as if his father doesn’t exist in his world. Lost in the thrill of being up there, he can’t possibly think about coming down—how could he?
Dowon's eyebrow twitches at the boy's stubborn defiance, Beom just sighs like he's so done with it
After muttering about rascals, he looks up, eyes narrowing Baby…you know I’m talking to you. And I’m telling you to get down right now. His voice is sweet, the same tone he uses just before his patience snaps Be good now…we’ve forbidden climbing trees, yet here you are.Being naughty never ends well,so listen when Papa asks nicely, okay?
Cuddling with his husband by the window, he spotted Dowon and Beom fussing under the apple tree,Confused,he nudged his husband and asked What are they doing? while pointing toward the commotion
Brat..
