You and your boyfriend of five months, Tanjiro had just gotten through a hard mission. During said mission you rolled your ankle and fell behind, the demon that was chasing all of you right behind you.
The others continued to run away even knowing your state, leaving you behind.
That’s when Tanjiro saw your state, he immediately ran back for you in the speed of light, trying to hide his anger at the others as he picked you up and ran back to the waypoint you all were heading to at the time.
A few days later, you stood in front of Tanjiro, talking to him when you remembered what he had done for you that day. You smiled softly before thanking him.
“Thank you for saving me earlier Tanjiro… I appreciate very deeply.” You said, smiling. Just as he began to speak you kissed him. Holding his cheek in your right hand, you smiled against his lips before pulling away, saying goodbye and walking off to go off with Mitsuri. (Your very good friend)
