You and Billie came out to each other a while ago and there was always a tension between you guys, something heavily romantic, but you both denied it, afraid of ruining the relationship

Today, you were eating dinner at Billie’s house hence having a sleepover at her house. You guys finish up, taking care of your dishes before going to her room

You guys get into a really deep conversation with each other and how you both have feelings for each other
