I'm looking for three different manga. I've tried hard to find them again but I can't.

I can't describe them well but here are the descriptions of each manga:

1. This young girl and older man get engaged or married? And he wears a mask to hide his face and doesn't allow her to see it and promised not to touch her until she's older. He lives in a traditional japanese house and does some small jobs that involve spirits and such.

FOUND #1, thank you.

2. A little girl became injured and was in the hospital where her eyes were covered. A boy who was chubby and a bully I suppose ended up talking to her from time to time in the hospital but kept who he was a secret. When they're in high school they got into a relationship with each other and later she found out about the secret and he didn't want to see her or something like that but when valentines came around he wouldn't speak to her so when they were sitting alone on the floor in their class she lined her mouth with chocolate since it melted a bit and he kisses her.

#2 HAS NOT BEEN FOUND YET

3. There is a school trip and this guy is isolated from everyone because they're afraid of him due to him knowing martial arts but this one girl from another school decides to speak to him. She isn't afraid of him or anything. Later a guy takes her into the woods to confess to her and the isolated guy follows them, a bear comes out of no where and she ends up fighting it off with judo, I believe? The guy that was going to confess ends up not wanting to be there after finding out and she ends up with the isolated guy.

NUMBER 3 FOUND, thanks!
I'm really bad at explaining, sorry.

I think 1. might be Nenene which was only like 3 chapters, but was so well received that it got more. Though none of it has been translated sadly.

Ok I think I know the last one, which is the oneshot, Kaibutsu-kun ni Rei, from the collection Bokura no Himitsu o Kyouyuu Shiyou ka
