looking for some series i read on a app a few years ago

hi. I dont know how long ago. 4-5 years? im not sure. i read some manhwa in a app on android. there was tokens for reading. i think app name was beggining with t. anyway in that app there was 2 series i really like but i cant find them. i think the app is gone. ı really wanna read them again.

there was one that a 30 yo woman was looking like some rich and spoiled 18 yo teenage girl and her parents hire the 30 yo for taking her classes for her. teen was in vacation on some island and our protagonist was going her school and living with a gay blond guy (i think he was her bodyguard?) and in the end start dating with a guy from school. the name was like back to 18 or something like that i think

for the second there was a grey haired fat girl. she was depressed and try to hang herself on a tree on a hill. but the rope break and she roll down to some trash of a restorant or cafe. the employes was attractive and i think there was 3 guy and 1 girl. (1 girl and 1 guy was siblings. they have black hair.) they help our girl to lose weight. ıt was a comedy manhwa

also if someone know the app name i can look from there too so i will write couple of manhwas i think was in the app.

the app had "bloody sweet" from what i remember but when i look at it it shows tappytoon and i think the app was not it.

there was a human teacher in animal(?) school. everyone was a animal but teacher was just human and human was rare in there. ıt had a cute style

I dont remember much else. does anyone know something

sorry if i butchered english.
