Happy twogether
Dreaming of the dokkaebi
Turning
The 11th school trip
(All of them except happy twogether have more action,the level of action in each kind of increased down the list, highly recommend these tho they r really good,with good companionships and relationships,good world building and plots as well with no muddy confusing storylines)
