Not always but often, you will feel a noticeable tension or conflict of personality for those born under the 4-10 Sun sign pattern. Reason of conflict may be either you are not allowing your partner to say something or your partner is doing the same thing with you. One person may be restless because of this type of behavior. There will always be some degree of mental and emotional restriction for various reasons.

But if other planets between the two horoscopes especially the moon (moon denotes your inner feelings) and the ascendants are having good relations than an intense devotion, loyalty and respect will be there between both of you. If ascendants and moon of two horoscopes are in unfavorable axis than your relationship will be tense and difficult indeed.

So just checking your compatibilities by only sun sign pattern is not full proof system of match making. So it is better to get your horoscope matched by a qualified astrologer.
