I hate to say this but I friggin missed it. There's no one to blame. Not myself for being so forgetful. Not Alex for not waking me up because I haven't told her about it on the first place. Not Dake for not hearing my phone when he called because it was totally out of battery.
In courtesy of istorya.net, I copied most of their photos and pasted it here. I just can't believe I missed it.
