can someone please help me?

I have you ever felt stupid for not remembering the title of some really good manga that you read long ago so now you're stuck with a hole in your heart? yeah it's sad and frustrating...scenes suddenly struck my mind... scenes from shoujo manga that ive read long before ive created an account bc i thought I'd only read for a short while ahahahahahahaha please help me remember these stories

SHOUJO MANGA 1:
all i remember is the girl's name is Yuka(?) and somehow her mug which her grandmother have her and has her name on it got broken. While she and the main guy were going on a date, she got lost and suddenly cant find the guy. after a while, in the bus stop, the guy gives her a mug (puts it on top of her head) but the spelling was wrong "Yuki"(?) soooo that's all i can recall pls help me TT

SHOUJO MANGA 2:
the girl has just arrived in the city (she just got out of the train) and because there were so many people, she got pushed, and her face slammed on a poster of an idol, making him look like he has a mustache (her mascara lol) and then ofc the guy got mad and wanted to know who did that etc etc they developed feelings for each other etc etc idk anymore that's all i remember TT

SHOUJO MANGA 3:
the girl and the guy are quite far apart in age... i only remember the part where the girl was on the phone with the guy, i think they were breaking up, and suddenly the guy leaned on her shoulder and said "dont leave me" or smth it was a really sweet manga TT

please help me recall these precious bbies i shouldve remembered their titles beforeeeee thanks
