Tension-less Supportive Lovers (they don't break up or mistrust each other)

Features couples who get together fairly early in the series, and stick to each other. No breaking up, no misunderstandings, mistrust, no 'staying-away-from-you-for-your-own-good'. In fact, there is no break up even in the end - (We all know that breakup in the 2nd to last epi, then they get back together in the last 5 minutes). They love, trust, and support each other. It may not be explosive chemistry, but its deep caring feelings that a true relationship is built on.
