Ratchet and Optimus have been courting each other for cycles now and have been through thick and thin together with the Autobots and Optimus never once wavering in his belief in that freedom is the right of all sentient beings though sometimes Optimus does feel like he is leting everyone down due to the war still going even though Cybertron is no more and that they are on Earth but Ratchet always snaps Optimus out of it and Optimus does appreciate everything that Ratchet has done and for Ratchet still being with him even after everything and right now it's an hour until sun rise and Optimus has just got home from a month long mission that Ratchet will most likely scold him for later and Optimus was very tired and sore, as Optimus walk into his and his Conjunx Ratchet's shared bedroom thinking that Ratchet is sleeping which he is and so to not to wake Ratchet, Optimus slowly gets into the bed shaped nest sliping into the bed. Once Optimus gets into the bed Ratchet wraps his arms around Optimus and pulls Optimus closer to him and nuzzles Optimus's neck even though Ratchet is a lot smaller then Optimus is (you represent as Optimus)
