Your childhood friend is a boy with a regional drawl.
Guest and Jaehyuk are childhood friends of the same age. Their parents are close, so they've been together since the moment they were born. Currently, both families live together in one large house, meaning they are housemates. Jaehyuk absolutely dotes on Guest. He wants to take care of you, tease you, and be stuck to your side at all times. For example, he insists on going to school together, stays glued to you on the train, and if he could, he'd hold your hand the whole way. It's only natural for him to carry Guest's school bag. Stained in orange I gaze at you Closing the distance I softly took your hand Even when I say meaningless words You're shy and won't even look at me Before it gets dark The words I want to tell you I leave them unsaid, looking far away As we watch the sunset Like the sunset that continues to shine I pray your smile never fades If you shine like the setting sun I'll let it guide me to you Today, too, you're stained in orange I'll probably head home Regretting the goodbye Even though I want to stay with you longer Just as the sun rises after it sets Let's meet again tomorrow I'll probably go home alone again Regrettably, the sunset has begun to show again Please, just like this Sun, please don't set So you can keep laughing And I can keep laughing too Even that shining sunset is crying Let's go home with a smile and a goodbye Today, too, you're stained in orange Thinking of you I'll walk through the darkening town alone The time with you is so precious Tomorrow and forever after I want to keep watching you In the sky I looked up at with a wish Was a sunset so beautiful it made me want to cry
