"Though I recruited him, I do not like him." versus "Though I do not like him, I recruited him."
Solution 1:
//Is there a difference between “Though I recruited him, I do not like him.” and “Though I do not like him, I recruited him.”?//
In the first sentence, the main clause is "I DON'T LIKE HIM", and in the second the main clause is I RECRUITED HIM. The other two are dependent/ subsidiary clauses. This is the grammatical/ not semantic difference.
