I can't find episode 19!?!?!?

Pft idk. I don't even understand myself ┗( T﹏T )┛I'm a strang child. This is a random question but what is a good manga u have read cause I'm trying to find one ( I'm a sucker for school romance, it's weird I love romance in anime and manga but I hate it in reality I think theirs no point (yet) ya know)

BUT I really do hate it when there titts are one size WAY to big

In a general sense, I can agree with you. There are some art styles out there where they give every female character ridiculously exaggerated proportions and balloon breasts. It's not appealing to me and it interferes with my suspension of disbelief.
In the case of Re:Marina, she's the only large-breasted character of the small cast, and her breasts are drawn with a fairly realistic drooping oval shape and weight comparable to women in real life who have extremely large natural breasts. I can accept at least that much, having known a few women with that body type.
Marina reminds me of another heroine in a manga that I forget the name of, but it's been at least a few months since its last update. She's a housewife with gigantic breasts, the story is slice of life following her perspective, and you barely see the husband and he never speaks or shows his complete face.

Ah, found it with some tag-searching. The manga is called Okusan.

Hehe, nice, I'm glad my efforts at searching for it proved worthwhile.
Those two are as cute as ever
