J'ai faim :/

Il est (9:38 de la nuit) 21h38 ici en Corée.
Mais j'ai faim.... Pourquoi ?! J'ai dîné il y a 3 heures (aparavant=auparavant) !
Je voudrais manger du Ramen.. Mais (je crains) j'ai peur de (me) grossir :(
C'est à cause de (toi) mon frère !
Il m'a (rendé avoir) donné faim :( (il) C'est un diable......il a commencé à manger.. Il (toujours) me fait toujours grossir (grosse). :P
Je veux de la glace aussi. J'aimerais (espère) qu'il y ait (aurait) une sorte de livraison de (la) glace à domicile..
Wao. Mon journal semble très puéril. Haha
Fin !

- 21h38 : in french we usually write hours from 1 to 23 and then the 24th hour is called "minuit"(midnight). And we write "h" after the number of hours instead of ":" in english. To differenciate 9am from 9pm, you can also say "9 heure du matin" or "9h du soir"

- auparavant/il y a : "auparavant" means "before", you can't use it with a measure of time. You could say "j'ai dîné auparavant" meaning "I had dinner before". But since you use "3 heures", it is a measure of time, so you should put "il y a" in front of the time and voilà ! It works with hours, day, weeks, minutes, years... Any duration. 

- du : I'm not sure about this one. You should put an article in front of the noun. But "ramen" is not a french word so there's no rule about using a definite or indefinite article. You could also say "un ramen" but "du ramen" sounds more natural to me :/

- j'ai peur de grossir : "je crains de grossir" is also grammatically correct, but less common. We tend to say "j'ai peur de" to say "i am affraid of"

- Grossir : the verb "to get fat" in french is "grossir" and not "se grossir"

- à cause de : "it is because of"

- donner faim : litterally means "to give hunger" meaning to make someone hungry. 

- j'aimerais qu'il y ait : J'aimerais (= I would like/ I wished) + Subjonctive of the verb "avoir"

- Livraison de "..." à domicile : "..." home delivery 

Hope it helps ! 

Bon courage 화이팅 !
