Love Across Time and Space

You study hard for twelve years, get up before dawn and stay up late to attend a junior college. Can you handle that?

During my three years at junior college, I met all sorts of people and made a few good friends.

But what I can't understand is why, after getting girlfriends, they always miss the ones they dated before.

Is it a dream of old love, a deep attachment to a former lover, or just simple lust?
