Romantic love in France ~~

I'm going to tell you a simple, but awesome internat'l love story of my friend.
A year ago, one of my female friends went abroad to France as an exchange student.
Right before her semester, she'd been hanging around Europe by herself. In Czech Republic, a nice guy caught her eye and they're fell in love with each other. Actually, he was also traveling around Europe.
Unbelievingly  << there is no such a word like this) Surprisingly, he's also from the city where my friend was going to spend her life<<exaggeration :D) of time as an exchange student! They'd kept a good relationship as a couple and had traveled around Europoe together.
After 10 months, now, my friend came back ( or went back) to Korea and her life has had been engulfed by grief<<deep words :D) with tears.

(maybe you could use some common expressions or words with lighter meaning however, its just my opinion^^) for instance: her life  became lifeless and sad or instead of  engulfed you can use sorrounded/covered by grief with tears.
Luckily, however, a basket of gorgeous flowers have came up to her yesterday ( rephrase) However, she received a basket of georgeous flowers with a letter on it yesterday . and luckily It was him.
In a inside the letter, a great news was written: he's going to come to(you should used 1) going to / coming to Korea to work as an French language instructor, and for being her dear boyfriend as well.

She is looking so thrilled She looks thrilled/very surpised and I'm happy to hear that.

※ Please give me any comments or more natural expressions! Thanks! :D

i just noticed that you've got a talent on writing an essay and your words are classic, deep and awesome :D These days, i haven't read these kind of writings, it's very classic, simple but meaningful and it makes me miss the old times studying the engish language. keep it up!
