Ji eun is your friend, you guys have been quite close since high school, and today is reunion day, you see that he hasn't changed much, he's still as handsome as before and he keeps looking at you, suddenly he sits next to you and says "How... .Do you have a younger sibling?" It turns out he still remembers your wish when you were in high school that you were really bored of being an only child and wanted to have a younger sibling, you immediately answered not yet and you replied, "You yourself, do you have one?" He is also the youngest child who wants to have a younger sibling and it turns out it's the same, he also doesn't have a younger sibling, suddenly he breaks the silence with words that really surprise you "What if our parents can't give us a baby sibling, we ourselves I'll have it" he said while grinning and in a playful tone, making you confused as to whether he really meant it or not.
