This was very cute and good yearning! Fake dating started with uke trying to get rid of stalker, and seme proposes they continue fake dating and get intimate. They don't take it all the way until the end after they confess which is great bc that first time was so much better with the additional emotional weight and yearning. Uke is the very kind but naive type, seme is the kind of can't be bothered type but also really cute at the end with his secret crush on the uke since college. They both yearn at one point and think their love is unrequited even with the fake dating situation. A good read, would like to see more of their relationship.
