Far be it from me to be so blunt about these things on any other day, but I believe that the time for watching and waiting is over.
Umi,
Clef - it's high time that both of you got over your hangups and admitted your love for one another. It's obvious that you'd be a wonderful couple, because your personalities are similar and yet not so much so as to seriously get on one another's nerves. For example, you're both... rather high-strung individuals, yet you each run around trying to get the other one to relax a little. It's adorable! What could be holding you back, the age difference? Clef's height? Love is blind! You should embrace it!
