"Appa, it's been a month since you're gone. I'm doing fine, even though there's a lot more homework nowadays. Hwaiting! Saranghae."

"Appa, it's been five months and I really miss you. My friends are slowly leaving me because of me being too 'mature'. Appa, is it wrong? I am growing up after all, right? Appa, help me. I'm lost. Saranghae."

"Appa.. a year has passed. I miss you much more than before right now. As much as I say I'm doing fine, I'm just so broken inside. I'm losing my hope. Help me.."

"A-Appa.. two years.. and my boyfriend l-left me.. I'm giving up.. can't I just join you? I want to! Omma and Oppa are trying to cheer me up but I can't. Homework. Social life. Relationships. Social Networks. I can't cope.."

"Appa.. help me. I have nobody. Oppa is soon going to be enlisted in the military service, Omma's getting sick. Please.. help me. I'm horrible without you. I'm hopeless without love. Please, Appa.."
