There is a person I've met at the workplace who I've become interested in since I was introduced to on my first day at work. The development of our relationship was slow due to being in a different department but we eventually got close enough to say that we're friends (she said to me that we're already friends) and go out for lunch with other colleagues as well every now and then.
After knowing each other for half a year, she got herself a boyfriend and to save money, she tends to buy a lunch box and eat in the office instead of going out. (Japanese setting)
About a month+ ago, I sort of heard something that she doesn't have a boyfriend now and I have always been thinking about confessing my feelings even when she had a boyfriend but couldn't because I am somewhat of an introvert or a person who doesn't speak much or just a coward who is not courageous enough.
We are both in our 20s (she is 2 years younger than me) and I wonder if it'll be awkward to ask her to meet for a couple of minutes after work to hand her a love confession letter personally.
It has been 3 months since I got moved to another office back in June 2017 so I think I can only ask her to meet me at some train station in the middle of her route going home from work.
