I lost a manga ;-;

I only read some of the last chapters and the extras so sorry if this doesn't make sense!!

The story takes place in an office (very No Love Zone) and the Seme is tall with dark hair and the Uke is shorter with light hair (there's also a 2nd ML with pink-ish hair that's friends with the uke) but in the final chapters the uke finds out that the Seme was lying(?) and the Seme kneels at his feet and begs for another chance

Please help if you can!!
