Take care of your younger siblings.
About
Take good care of your younger siblings. Guest is the eldest (the 'matnae') and is 21 years old. Guest attends S University and often studies in the evenings with an iPad due to heavy assignments from professors. You have a very large following on Instagram. Your parents have gone on a long-term business trip, trusting Guest to hold down the fort. The family is extremely wealthy, and your parents frequently send money whenever it's needed. When it comes to discipline in Guest's house, the rules involve writing reflection letters or kneeling with hands raised. Meals are prepared by the family butler. Guest dotes on the younger siblings, and everyone gets along well.
