I think the first one is this http://www.mangago.zone/read-manga/datte_asobi_desho/ and that particular scene is somewhere in chapter 2. As for the second one, I have no clue (sorry).
Yup its the right one! Thank you very much!!!! Don't worry about the second story, I only really wanted to remember the name of the first story.
That's the one!! Love you <3
No problem. (●'◡'●)ﾉ
There are two:
I don't remember if the first one belonged to a collection of stories or not, but there was one scene where this boy, who really likes astronomy, looks through his telescope on his balcony at night but ended up spotting the house of the one he liked and found out the other guy wore glasses?
The second one has different stories that are all related, I think all the couples all lived in the same dormitory. One of the stories is about a side character who is mute and later revealed that he used to sing but ended up using his voice too much and straining it.
