Help me find this BL

Sot he story goes something like this

> Uke and Seme both acrt as if they're a couple but by the end of the first chaper we learned that the seme actually rejected the Uke before

>Uke is actually in a "relationship" with an older woman who already has a partner because that was the only way he'd keep his mind busy from the seme

I cant remember what happens in the middle but its somethung like,,,,,

>>Seme and Uke got together but the Uke said that the Seme only accepted his feelings bcs of pity and he left, leaving only a letter in the seme's jacket ((he put it there when they were shopping/eating out))

>>Seme reads it a few months (?) then wents to Uke's house to find that he was moving away



I pretty muched butchered the story hut its been awhile since I've read it aaaaa


Ig if it helps, the cover is the 2 of them facing each other and their hands are covering the other person's mouth

And the title is something like "thing's we can't say" (?????)
