Stefan (Phen) is an amiable and funny guy. I'm sure there are other more suitable adjectives you could use to describe him but these are the two main qualities that strike me (I'm sure there are more...). If you read some of his entries, you might get a feeling that he's some sort of 変人. Well, you're not off the mark---he even admits it... lol. But that's what make him so interesting, it's part of his charms. We share a lot in common, including (but not limited to) being 変人. He lives a healthy lifestyle by eating 超-healthy foods and doing various physical exercises. His Japanese is nothing short of being amazing. The essence of his learning methods are quite similar to mine too, which is to have fun~ ^^

Phen's journal entries are really special and impressive, I always can't help smiling while I'm reading them. I feel from his entries that he is an interesting person and full of energy. I believe that his life will never be boring. ^^Yeah, we'll be good friends because we all like One Piece. Really happy to have met you Phen. ^^
