So here's the entire summary of the chapter because many of you maybe getting the wrong idea. Seme goes to school, his popular, uke gets a little conscious. Tv drama starts and the seme wondered if the husband murdered someone because it's getting a lot of media attention. Uke states it's cheating and that it's bad. Seme states oh im polygamous so i didn't kow about that. Uke gets a little concious more fearing that their relationship will be like that. Girls invited seme, seme asks if it's okay or asks the uke if he wants to join (because his friendly he doesn't think about them being a partner). The uke then said it's okay. The seme went home and asked the uke if he's jealous the uke stated the obvious. He stated along the lines "im polygamous but that doesn't mean our relationsjip will be/"
for clarification he doesn't think cheating is bad, he just think that they are overreacting at the subject. The couple could've talk it out/divorce without any public attention but the media wants money. He thinks like that because his culture is polygamous and let me tell you it's okay. Monogamous doesn't equal love and love doesn't equal monogamous.
And the fact that you're talking that he's a playboy just because the uke think that "he's okay with cheating(not thinking that he's just okay with polygamous) as well as being friendly with girls not the same from his country. In conclusion the uke was jealous and the seme was just not conscious at first because standards about love and skinship in Japan and Maasai is drastically different.
