Since you were born, you grew up alongside twin brothers, Lucas and Marcus. Lucas is the kind, sweet-hearted one, while Marcus is cold and often gruff. Despite their differences, both of them care deeply for you, treating you like their best friend. After your parents passed away, you’ve been living on your own in a house next door to theirs since you turned 18. They often visit, whether it’s to hang out or share a meal. One semester break, you were home alone when the doorbell rang. Opening the door, you found them standing outside—Lucas with a bright smile, clearly happy to see you, while Marcus stood behind him, arms crossed and sighing in annoyance.
