First is about about a guy running away and he met someone along the way. It turned out that the person he met (and fell in love with) was the arranged fiance of his sister. I think this was a light read with a comedic humor with it.
Maybe that one:

Most probs a oneshot from a collection of stories manga.
The guy was pretty insecure. He dreamed that there was a magical male fairy cursing him. In real life, a guy confessed to him but he didn't believe it bc of the dream. His dream mentioned that someone was going to fall in love with him, but after the kiss, the other party will fall out of love. He said to the guy who confessed to him that he was cursed and he also said about the kiss. So the guy who confessed forced himself to the guy with a kiss and said that he was really cursed. The guy shed a tear and the guy who confessed told him that he was just messing with him.
Guyys I think I find it ε=ε=(ノ≧∇≦)ノ check this out http://www.mangago.me/read-manga/koiyume_lover/mf/c001/1/

Is it this one? http://www.mangago.me/read-manga/koiyume_lover/
The first yaoi manga I'm trying to find is about a highschool student who went to the chem lab and met a guy. They got to know each other but the both of them noticed something off but they ignored it anyway. Their feelings developed and they had sex. Uke was left in the chem lab ass naked and shortly after he woke up, his father arrived. It turned out that their timelines overlapped and thus meeting in the chem lab once in a while.
The second manga i'm trying to find is about a guy who likes his uke very much (the manga started with them not being a couple, I think?) but whenever they had sex, the uke doesn't get off. The seme was concerned bc he was thinking that the uke wasn't pleasured while having sex. So the seme assumed (or someone advised him, I think) that maybe the uke has some kinks. He assumed that the uke likes S&M but the uke denies. Shortly after, the uke was waiting for the seme in the room, but he saw a rope (??) and he was curious so he tied his hands by himself. He was too successful bc he can't untie it (lololol) so when the seme arrived, the seme went to the uke and had sex with him (with the uke's hands tied). After they had sex, the uke explained that there was actually a problem (i forgot lol) that he can't get off after sex (I think??). Uke said that whatever they do gives him (uke) pleasure.

Where the 2 guys (rivals in love) liked the same guy but the rivals ended up being together hehe I think it's also a school life? Not sure but Guy1 and the liked person go to the same school.
