Yaoi Manga Title needed part1

1. Seme won’t let himself love again because he believes that it killed the guy he loved before. But it’s an accident, they’re on a high building balcony and the wind was strong & the guy(seme’s love) stood on the railing/fence/beam, he’s urging the seme to be honest with his love for him/take action or he’d jump. Unfortunately, as the wind was strong so he was swept off.
They’re friends/close so seme don’t want to ruin current relationship, gay too. Seme’s a business owner, eventually falls in love with a younger guy/working for him.. or something like that

2. salaryman1’s friend&coworker salaryman2(virgin/inexperienced in Love) fell in love@first sight with the guy delivering mails/papers in their company(salaryman2 described him as/with an angelic smile, shoulderlength hair). He confessed, deliveryBoy’s reluctant @first, but they’d became couple eventually (after a serious talk by the company’s rooftop).Some part of the story is in salaryman1’s POV, thinking how’d his friend became gay so easily, but still supports them anyway

3. Uke was cooking some noodles, seme (just out the bath) ask him to share. Uke’s complaining that it’s barely enough for him, but splits the food anyway, seme’s unemployed & uke just got back tired from his part time job. Uke saw a fresh scratch mark by seme’s back(he knew it’s not from him meaning seme cheated on him again). Uke ran away crying saying he had enough, he went to a guy friend’s clinic (he’s a medical practitioner, idk what field) complained & left. Uke met his ex(married salaryman) asked him why he’s still not divorced & why’s he still fooling around. Ex answered him that it’s for fun but he loves his wife that’s why he keeps coming back to her.
Seme went looking for uke @the friend’s clinic & got scolded.seme explained that he had affairs (only to People that’s close to them/knows them) bec the makeup sex w/uke is great, & it makes him realize how much he loves uke. Friend told him to stop cause it’s hurting uke, & will dump him eventually. Then they went looking for uke.
On the way home, uke met the guy that recently slept with seme(he’s obviously in love w/seme), he pushed uke along the stairs saying that uke should be gone so seme would love him instead. Fortunately seme&friend was @the scene and catches uke.. commotions..Happy ending eventually. Last scene was the couple went to friends clinic asking him to take care of them for the time being(asking for free food) bec they haven’t received their salaries yet, both now employed.

Help please, they’re just extra stories, not really the main story so it’s hard to search for them. I’ve read them before but I forgot their titles (they’re not really that old time manga, but I’ve read them 4-5 yrs ago..
