올해로 데뷔 9년차에 접어든 플라이투더스카이는 자신들의 외로움이 후배들과의 거리감에서 비롯된 것이라 했지만, 과거 연인과의 이별이 더 큰 원인인 듯했다. 두 사람은 1년 터울로 각각 3년, 10개월 사귄 여자친구과 이별의 아픔을 맛봤다. 今年出道9年FTTS自己孤单是和后辈的隔离感等,但是好象过去恋人的离别是更大的原因,两个人相差1岁,各自和交往了3年,10个月的女朋友离别更痛苦. This being the 9th year in the industry, instead of saying that the distance between the juniors caused them to feel lonely, it seems that the main reason is their breakup with their previous lovers. Both of them have a 1 year age gap, and had just broke up with their girlfriends whom they have dated for 3 years and 10 months respectively. This caused them much more pain.
환희는 3년 사귀던 연인과 지난해 1월 헤어진 뒤 제대로 사귄 여자친구가 없다고 했다. 브라이언도 지난 3월, 10개월 동안 만나던 여자친구와 헤어졌다. 그래서 두 사람은 입을 모아 “사랑이 그립다”고 했다. FANY交往3年的恋人去年1月分手后说绝对没有在交往的女朋友。BRIAN也说3月份的时候和交往10个月的女朋友分手了。所以两个人异口同声的说“希望得到爱情.” After breaking up with the girlfriend he dated for 3 years last January, Fany says that he is not seeing anyone now. Brian also says that he broke up with his girlfriend whom he has dated for 10 months in March. Thus both of them says that they "yearn for love".
환희는 “지난해 6집을 내고 ‘윤도현의 러브레터’에 출연해 ‘활동을 시작하면 만나던 연인과 꼭 헤어지게 되더라’는 말을 했는데 진짜 이뤄졌어요”라며 “외로워요. 이번 앨범도 외롭고 쓸쓸한 앨범이예요. 여자친구가 생겼으면 해요. 특별히 이상형은 없고 그냥 느낌이 좋은 여자면 좋아요”라며 쑥스런 미소를 짓는다. FANY说“去年6辑出来参加‘尹道玄的情书’里说‘开始活动的话和交往的恋人一定会分手’这样的话真的是变成现实了”还说 "很孤单,这次专辑出来也是孤单,凄凉的专辑.想交女朋友,没有特别的理想型,只是想个感觉好的女生交往.”说的时候不好意思的微笑。 Fany said that he mentioned in june last year during YDH's loveletter that when he starts his activities for his new album, he will definitely break up with his girlfriend. His words became reality. He even said"very lonely, when we release this new album, i felt lonely too. i want to have a girlfriend too. I dont really have an ideal type of girl, I just want to date a girl who makes me feel good." after sying this, Fany smiled shyly.
브라이언도 지난 3월 성격차이로 교제한 지 10개월 만에 헤어졌다면서 “내 일을 잘 이해해주지 못했고, 데이트 스타일도 서로 좀 달랐어요”라고 밝혔다. BRIAN也是在3月的时候因为性格差异和交往10个月的恋人分手了,“我的事情她不能理解,date style彼此也不一样” Brian has also broken up with his girlfriend in march after dating her for 10 months due to differences in personality. "She cannot understand me, our date style is totally different."
상대의 실명을 밝히지 않았지만 환희가 “(그 여자가) 신인이어서 그렇다”고 말해 연예인이었음을 털어놓았다. 브라이언은 “이해심이 넓은 여자, 만나면 재밌고 마음이 열려 있는 사람이 좋아요”라고 이상형을 밝혔다. 虽然没有说对方的实名,但FANY说“(那女人)是新人”颤抖的放出了对方是演艺人。BRIAN:“理解心很广的女人,见面的话很有意思,可以打开心扉的人就好了”这样说出了理想型。 Even though Fany did not reveal the name of the girl, he said "she is a new artiste" which reveals that the other party is also a artiste. Brian said "an understanding girl, a person with an open mind will be interesting to talk to" and thus reveals his ideal type of girl.
새 앨범을 소개해달라는 말에 이들은 “외로움과 쓸쓸함이 담겨 있어요. 다음 앨범에는 사랑을 담고 싶어요”라며 장난기 어린 말로 설명한다. 接着介绍新专辑的话 两位用开玩笑的语气接着说:“浸入孤单和凄凉,下一张专辑里希望可以浸入爱情” when introducing the new album, both of them jokingly says: "this album is injected with loneliness, we hope to have love in the next album."
okie.. that's about it..

Fany did also say that the next girl that he will be dating will be his angel as well.. but lazy to translate that part!

okie it's good to know that we all agree that dongwan is cute. hehe..

he spilled so much beans about brian..funny..
spyang: i totally understand what you mean by that girl.. that it's both good and bad that brian falls in love easily...

okie.. let's not question his faithfulness.
missflowahh: according to this piece of news, he should not be seeing anyone now...

brian does give me the impression that he's more reserved.. hwanhee said on the show that he doesnt really discriminate any type girls, he will just give the relationship a shot if he feels not too bad about a girl.. for brian it's not the same..
irene: dont think it's jung ryeo won.. think she's the first girl he dated who two timed him and junjin.. hey why didnt dongwan spill the beans about this?! (

so mean of me..)
OMO! this is a super long reply.. and i have lots to say.. will post this first. will go for a bath first.. be back with some interesting stuff about 21st July's Jihwaza!
