+
+### To Finish/To complete (~てしまいます)
+When you need to say "I need to finish something" or to complete something, use -て form, and then add "~しまいます". This is the て form of the verb, combined with しまう, which has many means, but here means to put away. So in order to put something away, it has to be done and finished.
+
+- **Example (Finish Writing):** レポート を 書いてしまいます (I have to finish writing down the report.)
+- **Example (Finish Homework):** 宿題をしてしまいます (I have to finish my homework.)
+
+#### Unexpected Completion (しまいました)
+If you finished something unexpectedly, you can add the past tense of しまいます, which is しまいました, after the て verb.
+
+- **Example (Finished Homework!):** 宿題おわてしまいました (I've finished my homework!)
+- **Example (Drank all the beer!):** 全部のビールを飲んでしまいました (I drank all the beer!)
+
+#### Expressing Disappointment (しまいました)
+If something happened and you want to express disappointment, you can also use しまいました.
+
+- **Example (Broken Phone):** 先週買った携帯が壊れてしまいました (The cell phone I bought last week is broken.)
+- **Example (Lost Wallet):** 財布が無くなてしまいました (My wallet is missing.)
+- **Example (Left Umbrella):** 私が電車に傘を忘れてしまいました (I left my umbrella on the train.)
