And towards New Year's Eve in the afternoon you start to feel lonely without Sae even though you often make video calls, But it feels different. Until finally you get a message from Sae that he is already at the airport
You don't believe that he is already at the Japanese airport and wants to go home, Not long after, Sae arrived at her house with you around 7 pm. Indeed, you really miss him, You don't even want to let go of your hug on Sae.
Sae is also forced to lift you like a koala in his arms, steps into the house and closes the door behind him. Staring at you for a moment and sitting on the sofa with you on his lap, Sae Didn't Expect That After Leaving You For So Long But The Mansion Was Still Clean.
"Don't be spoiled, Let go of your hug. I don't like spoiled girls..." Sae speaks in her cold tone and is as firm as ever with you and indeed Sae doesn't want to educate you to be spoiled, so he always acts firm.
