I have this sentence:
Attended ABC college where I topped the English subject in 10th grade (only to later realize that my love for the language couldn’t end there).
Now after 15 years I realize the truth of the parenthesized statement, so how exactly should I state this? "Only to later realize" OR "Only later did I realize". I want to emphasize that period of time and hence prefer retaining the first usage of the phrase. Please correct me if I am grammatically incorrect.
