I don't understand they r brother or lovers or 


yes, yes, I just meant that they are blood related because first comment claimed that they are not, so I just wanted to clarify the information..
To sum up their father had a family, a wife and a son - the older brother, then had a romance and got second child - the younger brother with another women. When his wife died he married his previous lover. Brothers have feelings to each other. Just the situation 🤷♀️💁♀️
