Please help me with my law subject. Thank you.

In the t of anger, Angelo uttered quite loudly that he would have Jon killed for P20,000 for sleeping with the former's wife. Upon hearing Angelo's utterance, Mike offered to do the deed for him. Angelo paid Mike to execute the plan. When Angelo's anger subsided the next day. he told Mike to forget about what they talked about the night before. Does Angelo have the right to recover P20,000 from Mike? Mariana, a beauty queen, has just won her first pageant. David, one of the pageant's sponsors, congratulated Mariana for her win. He then subtly proceeded to ask the lady to be his common-law partner for a year promising her P1,000,000 in exchange. Mariana accepted the offer. However, David did not make good of his promise. May Mariana recover from David
