mahwa/manhua (I think it was cn) where MC and ML are in high school, both poor (which is kind of like the main challenge for their relationship). MC stayed poor until he got part-time jobs in college, he was able to buy new black shoes that I'm certain, ML's family prospered through his father's investments during high school.
MC did confessed his feelings to ML but ML didn't accept it in a way because he was in denial but gets over jealous whenever some random guy makes MC smile. I can't pretty much remember all of the details but the main part is...
They always meet at this PARK and look at the stars at night. Sort of like expressing what they feel or their situation at the time.
where the setting was kind of like 70s - 90s. MC can see ghosts and ML was like finding for a job so he went to MC's house to be kind of like a butler or something (maid but for men). And the ML was the one to chase away the ghosts that was lingering on MC cuz of his yang energy (I can't remember). I'm kind of remembering that the title was 2 words?? Like first word ___ then I think the second word is 'Night' I could be totally wrong about the title tho.

Lf mnhwa where mc has this mermaid ancestry or sort of like that and he kinda like had a mermaid scale that came off from his mouth and iirc he doesn't want to get wet with water otherwise he would disappear. And ml was the one to be wedded to mc to stop this curse that the family has.
i think mc had star candies every time ml rejected him too? to keep him from dying? commenting in case some one else answers

I think I kinda remember that mc's mother had disappeared is that there's lingering bubbles. Idk if it was bubbles or pearls but I'm leaning more towards bubbles and mc doesn't want that to happen to him
Oh, I found it. This one https://www.mangago.me/read-manga/gone_with_the_bubbles/
