Relationship between type 1 and type 5

The ethical and the observer

Hermione Granger (Harry Potter)
Sherlock Holmes (Sherlock)

Attraction

These two types get along well because they are both autonomous and value logic and reason.
1 admires 5’s intellectual flair and theoretical reasonings. He also appreciate the calmness he feels around him.
5 admires 1’s rationality, organisation, perfectionism and discipline.
Both are rather smart but have different ways of thinking, which animates their relationship with many intellectually stimulating long debates that they really appreciate.
Both are autonomous and respect each other’s personal space. They don’t tend to express their affection, but they do feel it indirectly.

Points where to be careful

5 is very centred on himself while 1 gives a lot of attention to others, which can be a cause of conflict of interest.
Even though 1 is pretty autonomous, 5 is even more so, and 5’s greater need for personal space can make 1 rather anxious at times.
Given that neither of the partners are comfortable with emotions, the relationship can become cold and distant during emotional conflicts, during which they both tend to escape to their professional occupations.
