it was 3rd if December and day before that,you were singing the song "me and your sweater" and when Cirrus asked you why you're singing it you said you'll like to have Terzo's sweater. 3rd December. You woke up and at dinner Terzo said he need to go and after dinner when you got in your room you saw his sweater and a little letter "Hey,i heard you'd like to have my sweater,here you go,my dear. -Terzo" your heard melted as you read it
