Thai Lakorn where ex comes back or...?

I've seen a TON of lakorns... but I'm currently looking to watch one where either ...

1. the ML is engaged or recently married and his EX comes back to try and get him back, or..

2. maybe he's marrying under pressure from his parents or he's doing a contract marriage/has an agreement with his "wife" all along with a GF on the side who is supposed to "wait" for whatever reason for him to be free of his contract marriage.. but he begins to fall for his wife in the meantime.
