our MC is a soldier he and his troupe went to fight a war but MC was met with an accident and his space shuttle fell into a planet with no intelegent lifeform, There he met a tentacle blob looking creature which was very hideous to look at (it's our ML btw :⁠-⁠P) MC was r*ped by the ML in order to get his information or something. The planet's living environment was very harsh so MC treated ML as a tool to keep himself alive. As time went on their interaction became very sweet ML would listen to everything MC told him and would protect him from harm it was also funny how he would get offended when MC called him ugly but was speechless when he called him beautiful it was all very wholesome. They also very often had consensual s*x and ML also understood later that raping someone was bad. ML is a immortal entity like creature who is also stuck on this planet he has no emotions and at first he treated MC as a pet it was so funny how he sometimes copied MC's behaviour to piss MC off. They spend their days bickering with each other their openions are very different from each other and they often fight with each other, but after being stuck with each other for sooo long they both got character development and understood each other better, MC gradually fell in love with ML and told him I love you even though ML can't understand feelings and here comes the sad part MC had cancer so he told ML to leave him behind but ML started crying and told him he was long prepared to die with him that he (Mc) taught him how not to be lonely and he doesn't want to be lonely anymore then they both had some kind of spritual s*x or something and then we are back to the starting the first intelegent creature of the planet coming out of water with no memory of who he is laughing and crying sitting at the sea shore (it was kinda confusion ending but I don't dislike it (⁠╥⁠﹏⁠╥⁠))
