"Dudu du du du dudu du du duu duuuuu...." Si Jin humming a tune softly to himself, occasionally whistling another, all the way until he finally reaches his home.   When he enters, the living room is dark with only dimmed lights at the corridor, which he walked along before climbing the stairs to the bedrooms. As he passes by, he pauses outside Jae Yeol's room leaning against the threshold door when spotting two figures are still up and not asleep. Jae Yeol is sitting at his study desk, clicking the mouse and dragging it left and right, directing the cursor on the laptop screen. At the same time, he is apparently all ears to Jo Seok who is currently talking while lying down on Jae Yeol's bed staring on the ceiling, legs crossed and hands at the back of his head.   "Hey guys, what's up?" Si Jin asked, flashing a grin at the boys and making them finally aware of his presence.   "You just got home? Why so late, you didn't even reply to Jo Seok's message just now," Jae Yeol half wondering why this friend of his come back so late from usual.   "Aaahh, I was a bit busy. Guess I forgot afterwards. Hehe..," Si Jin sniggers. "Still with your project?"   "Naah, we are just chatting. I don't think I can go anymore, currently stuck with my simulation. I don't have any idea at all why suddenly my result doesn't match with the expected answers. Got to try find the bug again tomorrow. You stay back so late in the lab?" Jae Yeol queries again.   "Me? Nope. I actually bump into someone in the middle........," his sentence just left hanging in the air. Bringing up an indirect topic about Kang Mo Yeon suddenly makes him grin like a Cheshire cat without control, and certainly, that doesn't escape his friends' eagle eyes. After all, they have known each other for quite some time already to be familiar with each others behaviour.   "Hmm, someone we know? Seems like it is a very special person to make you behave this way," Jo Seok voicing out his observation, already sitting up to scrutinise at his friend closer.   "Well..... probably. I don't know..... I'll tell you guys later, alritey????..... I'm just too tired and the only thing that's been in my mind right now is my super duper lovely bed! Huarghhhhh!!!!!!!!" Si Jin faking a yawn and trying to show a sleepy face in his attempt to avoid their further question. He doesn't want to spill the beans just yet, somehow afraid of the possibility that it may drive away the person he just knew. Perhaps some other time, he thought.   "Yaaaa, yaaahhh! Why so secretive? Come Jo Seok, let's go beat him up and make him tell us now!" Jae Yeol quips to Jo Seok, both of them suspicious at his trick to run away from their interrogation.   "Hahaha! In your dream!!! Laterrrrr!!!… Si Jin doesn't waste anymore time and quickly escapes into his room, making sure he locks the door in case the boys are being serious. The only sounds that can be heard later on is his roaring laughter while his two friends grunted in frustration at the situation.   "Yeaaaah, here comes my sweet dream!" He screams out, drops his stuff on the floor and throws himself onto the cozy bed, in no time slumbers peacefully throughout the undisturbed night.   (Apparently Si Jin was indeed very sleepy, lol!)           *****************************       The day after, Si Jin's schedule is free as it is finally weekend. The boys go out together for a lunch, then having a stroll in town before ending their out-and-about with groceries shopping. They only cooks simple meals for dinner at home in the evening.   When the clock is ticking to nine, Si Jin is ready to go out again, at first trying to leave silently without his housemates' knowledge but unfortunately to no avail as both of them are in the living room at that moment. He then resorts by saying an excuse which his friends doesn't buy even for a bit, yet nevertheless, they let him go for the time being, not without a lot of persuasion and promise by Si Jin to buy them a special meal once he feels ready.   He is not someone who used to keep secrets from them, but for some reason he does this time. Does Kang Mo Yeon's characters surprisingly has a rub off on him already?     *****************************     As soon as he reaches the convenience store, he tries to take a peek at the glass window. Yet to his disappointment, she is not at the counter but instead only a young local girl is standing at the exact position she was the night before.   "Aissshh, doesn't seem like she is working tonight," he concludes. That makes him realises he doesn't have a clue about her shift timing, but then again, how would he know if she is so tight-lipped at the first place?   He enters the store nevertheless, not entirely sure how to fish for her info from this other girl.   "Ka-Chingg", the door ch
